A/N: Some of these will be darker than others so I'll put a little '*' next to them as a warning. This chapter will be a little longer than the others.

...

Clint Barton/ Hawkeye*

Clint was away on a mission so you were video chatting with him. He was going to be home in a few days and you were missing him like crazy. Suddenly, there was a loud noise heard outside of the room he was in.

"Hang on a sec, babe," he said, going to investigate. All you could do was listen to listen to the gunfire outside and you heard Clint scream, then it went silent.

"Clint?" you called hopefully. The camera on his end was picked up and taken out of the room. You were horrified when it panned over Clint's dead body.

"You're next, Mrs. Barton..."

*

"Clint!" you screamed. You sat up and started sobbing hysterically. Hearing you, cry out, Clint sat up and turned on the light.

"Y/N? Baby, what's wrong?" You crashed your lips on his and held him tightly, wanting to make sure that he was real. Clint was a little shocked, and when you pulled away, you sobbed into his chest.

"Nightmare?" he asked. You nodded and he held you tight, rubbing your back. Hearing you in distress, Lucky raced into the bedroom and jumped on the bed.

"It's okay, boy," Clint assured the dog. Lucky nudged you with his nose which made you smile a little and you scratched him behind his ear. Slowly, you started calming down.

"You okay now?" he asked. You nodded your head and started getting comfortable again. Clint switched off the light and held you in his arms. Lucky got comfy at the foot of the bed.

"Clint?"

"Hm?"

"I'm scared that you won't come home from your next mission." Clint kissed your forehead.

"I know, which is why when we start trying for a family, I promise I'm going to retire. I love you so much."

"I love you too, Clint." You fell into an easy, dreamless sleep.

...

Tony Stark/ Iron Man

You were coming home from your job at the tattoo parlour. It had been a rough day and all you wanted to do was come home and see Tony. You walked up to the bedroom and when you opened the door, you heard the sounds of moaning. On the bed, you could see Tony with another woman. Your heart broke into a million pieces.

"T-Tony? Wh-what are you doing?" Tony stopped what he was doing to look at you.

"What does it look like?" he sneered. Why was he doing this?

"I... I thought you loved me," you whimpered. Tears were streaming down your face.

"Please, I'm Tony Stark! Like I could ever be satisfied with just one woman," he scoffed and started laughing at you and the woman started laughing too.

*

You woke up in tears and looked at the man sleeping next to you. You freed yourself from his arms and walked into the adjoining bathroom to splash cold water on your face. That dream had really shaken you as it vividly played out in your head and you started sobbing. Hearing you, Tony got out of bed, entered the bathroom and wrapped his arms around your waist.

"What's the matter, babydoll?"

"N-nothing," you sniffed.

"Don't lie to me Y/N, I know you're crying. Tell me what's wrong." You turned around in his arms to look him in the eyes.

"Tony you would never... cheat on me, would you?" Tony looked shocked and really hurt by your question.

"Y/N, how can you even say that to me?" he asked, cupping your face and drying your tears with his thumbs.

"I just... I had this dream that you-" You were cut off by his lips pressing against yours.

"I can assure you that it was only a dream. Since I've been with you, I haven't so much as fantasised about another woman. You are my beautiful wife and I love you."

"I love you too," you smiled.

"Now, let's get you back in bed and I can show you how much you mean to me," he said huskily in your ear.

...

Pietro Maximoff/ Quick Silver

Today, Pietro was having some tests done on him and you were going along for support. You gave him one final kiss before they hooked him up to various machines. They started him on a treadmill to test out his speed. He started out on a steady pace to begin with and gradually picked up speed. Soon he was going so fast that you barely see him. You noticed that the equipment was starting to struggle.

"Is that normal?" you asked, feeling slightly worried about your husband.

"It'll be fine," they assured you. Faster and faster he went when all of a sudden, he vanished. You were slightly dumbfounded.

"Wha... what happened?" The scientists checked their equipment. They explained what had happened. Basically, Pietro went so fast that he went to another dimension.

"Well, can you bring him back?" They all talked to each other.

"I'm afraid we can't, Mrs. Maximoff. He'll be stuck there for all eternity." That's all they could say?! They had pushed him so far that he was never coming back to you and they treat you like you're stupid!

*

You woke up in tears and blinked a few times, looking at the ceiling as they fell down your face. You felt Pietro shift beside you as he slept, assuring you that he was still with you. You snuggled into his side and placed your head on his chest. Feeling your wet face on his bare skin caused Pietro to wake up.

"Y/N? You okay?" he rasped, his voice thick with sleep.

"Yeah... I just... had a bad dream," you said, starting to cry a little. Pietro wrapped his arms around you and kissed the top of your head. One of his hands ran up and down your back and slowly, you started to fall back asleep.

...

Thor Odinson*

Thor was away in a huge battle. Normally he would let you go with him but this one was far too dangerous. All you could do was nervously pace back and forth until he came back. Unable to take to anticipation of waiting, you went to see Heimdall.

"Heimdall, how goes the battle?" you asked.

"There have been many casualties milady, but we are becoming victorious..." He frowned slightly.

"Lady Y/N, I'm afraid Thor has been killed." You felt your heart skip a beat.

"Wh-what?" Heimdall opened the portal and the few warriors that had survived started coming through it. Lady Sif immediately went to you to hold you back as they brought Thor's body back.

"No, no, no... NO!" you screamed.

*

Your eyes snapped open and you were panting heavily. You blinked a few times as you tried to make sense of your surroundings. As your breathing settled, you realised you were in the safety of your bedroom with your husband sound asleep under you. You dried your eyes and kissed his lips. Thor smiled in his dreams and held you a little tighter. You rested your head on his chest and listened to his steady heartbeat, the sound assuring you that he was still very much alive.

...

Sam Wilson/ Falcon

Sam was away on a mission. Every day you worried about his safety, wondering if he'll come home or not. Whenever there was a news story on the Avengers, you watched it with great intent. You were folding the laundry when there was a news flash and you raced into the living room to watch it. They were all fighting against a group of terrorists but your eyes were for the most part on Sam. One of the terrorist placed something on his back and pushed him off the top of a tall building. Sam tried to open his wings but they malfunctioned. You could only watch horrified as he plummeted to the ground.

*

You cried out and tears streamed down your face.

"Y/N?" Sam asked groggily from next to you. You started sobbing and clutched at his top. "Nightmare?" You nodded your head and he hugged you tightly, kissing the top of your head.

"Sam?"

"Yeah, Y/N?"

"Please... be careful on your next mission. I know you will be but I can't help but worry about you when you're gone. I love you so much."

"I love you too. It's gonna be okay, because I have the best team watching my back." You snuggled into him and slowly started falling back asleep.

...

Natasha Romanoff/ Black Widow

You were on a mission with Nat. You were positioned in the Himalayas to destroy a Hydra base. Your mission was a success and you were escaping from the wreckage. You were both running along in the snow when Nat stepped in a hidden ice cavern and she fell through. She just managed to catch herself before she fell into the deep hole.

"Nat!" you screamed, and ran to pull her up. You tried to get closer to her but your extra weight on the ice caused it to crumble.

"It's no use, Y/N. You're not going to pull me up."

"I can... I can Nat." Tears were starting to prick your eyes.

"You'll die too."

"Then we'll go together."

"No, we won't. I'm sorry." Nat zapped your hands, forcing you to let go and she fell into the deep, bottomless cavern.

*

You bolted upright in bed, panting heavily as tears poured down your face. Your sudden movement next to her caused Nat to wake.

"Nightmare?" she asked. This was not uncommon between the two of you so you both knew just how to deal with this situation. You nodded and she wrapped her arms around you. You rested your head on her chest and she stroked your hair. She waited until your breathing had settled before she allowed herself to fall back asleep. Nat would never show it in an obvious way but she always put your needs before hers.

...

Bucky Barnes/ The Winter Soldier*

You were in a room that you didn't recognise. You felt like something was very wrong and you couldn't move. Outside the room, you could hear someone talking to Bucky.

"... in fact, we have a surprise for you," the voice said.

"Move, you have your orders," another man grunted. What orders? Wait, why were you moving? You entered the next room and Bucky's widened when he saw you.

"Y/N? What did you bastards do to her?!" Bucky snarled. A wicked sneer appeared across the man's face.

"We know that you would never hurt your lovely wife, so she's going to be the one hurting you and you're not going to do a thing to stop her." He was right about that; Bucky would never hurt you. So why were you hurting him? You could only watch helpless as your body attacked Bucky before taking out a gun and pulling the trigger.

*

"Bucky!" Your eyes snapped open and you were in tears. Bucky woke at the sound of his name being called.

"Doll, are you alright? What's happening?" You hugged him tightly and kissed his lips.

"I'm okay Buck. It was just a nightmare," you assured him. Bucky hugged you and kissed the top of your head.

"What was it about?" he asked.

"You, um... you had been killed," you sobbed. For his peace of mind, you wouldn't dare mention that Hydra had taken over you to kill him. Bucky whispered sweet words in your ear and stroked your hair until you fell back asleep.

...

Scott Lang/ Ant-Man*

Today, Scott was doing Ant-Man stuff with Hank while you looked after the girls. They were playing in the living room while you were washing the dishes. There was suddenly a loud noise coming from the other room and you heard the girls scream. You raced in to see Yellowjacket coming through a gigantic hole in the wall and advancing towards Lillian and Cassie who were huddled in the corner holding each other. He was almost knocked off his feet and Scott went back to his normal size.

"Y/N, get the girls out of here!" You did as he said without hesitation and hid the girls away. Once they were safe, you returned to watch the fight. They were shrunk so you couldn't tell who was winning. Yellowjacket suddenly went back to his usual size and you could see him grab something in his hand and crush it. He let it drop to the ground and you realised that it was Scott. You stood in the doorway in attempt to protect the girls but he just batted you out of the way. You could only listen as he took the girls away from you.

*

You woke up with your heart pounding in your chest. You turned over to see Scott still sleeping soundly next to you. Although it was just a dream, you had to go check on the Cassie and Lillian. You walked into the room that they now shared and saw they were sleeping safely in their beds. You watched them for a while when you felt a pair of arms around your waist, making you flinch at the sudden contact.

"What are you doing, babe?" Scott croaked, placing his chin on your shoulder. You smiled a little and kissed his cheek.

"I had a nightmare about the girls and I know it's silly that I had to come check them but..." Scott kissed your temple.

"I completely understand. Now, let's get back to bed."

...

T'Challa/ Black Panther

T'Challa was away to a place called the Savage Lands. It was difficult being without him, especially now that you were a few months pregnant but you were carrying on the best you could. It had been over a week since you last heard from T'Challa. Finally, you got the call from him; however it was not good news. He had told you that there was some kind of barrier put around the Savage Lands that prevented him from leaving. This was one of your worst fears. Although you could now call Wakanda your home, you still felt alone and now you were going to raise a child by yourself.

*

You woke up in tears and put your hands on your empty stomach. That's right... you weren't even pregnant yet and already you were worried about what could go wrong. T'Challa came into the bedroom, late from signing paperwork.

"Y/N? What are you still doing awake?" he asked. You were usually asleep by the time he came in.

"Nightmare," you said. T'Challa kicked off his shoes and joined you on the bed, holding you in his arms. After a while, he got changed into his pyjamas and eased into bed. You soon fell asleep, feeling comforted in his warm embrace.

...

Steve Rogers/ Captain America*

You wanted to surprise Steve by coming by the Tower. When you entered, you couldn't help but feeling something was very wrong. As you walked through the corridors, you could see blood splattered along the walls. Then you came across the first dead body. After that, that you just kept finding them. Tony, Natasha, Clint, all dead. You could hear the sounds of fighting and rushed towards it. Upon entering the room, you saw Bucky fighting with Steve. At first you thought that Bucky had relapsed and had caused all this damage but then you realised that it was Steve that was attacking Bucky. He suddenly spotted you and was horrified.

"Y/N, get out of here!" he screamed. Steve knocked him to the ground raised his shield and brought it down upon his neck.

"S-Steve?" He started advancing towards you. When he was in close proximity, you could see that his eyes were so dark brown that they were almost black. You backed yourself against the wall and he had you cornered.

"Why are you doing this?" you whimpered. Steve's face stretched into a nasty sneer and his hands went around your throat.

"Hail Hydra..."

*

You woke up screaming and fell out of bed. Your screams woke Steve and he turned on the light and tried to comfort you.

"Y/N, what's wrong?" You scrambled away from him and curled up in a ball on the floor.

"Stay away from me!" It hurt Steve to see you so afraid of him.

"Sweetheart, please. It's me Steve, your Steve."

"Tell me something that only the real Steve would know," you sniffed. He thought for a moment. While he spoke, you studied his eyes and saw they were beautifully blue with just a hint of green.

"When I was just a scrawny kid back in the days, I used to stuff newspapers in my shoes to make them fit. My mom could only afford to buy me hand-me-downs." This was definitely something only Steve would know. You threw yourself into his arms and he held you tightly.

"Are you okay? That must've been some nightmare." You clutched at his shirt and he stroked your hair.

"Y-you h-ad k-k-killed everyone... I-I think... H-H-Hydra had something to you and-and..." you burst into tears again.

"Shh, it's okay. I'm here for you," he soothed. Steve waited until you had calmed down enough before picking you up and putting you back into bed.

"Steve, will leave the light on?" you asked.

"Of course, darling," he responded, kissing your forehead. You placed your head in his chest and let his steady heartbeat lull you back to sleep.

...

Loki Laufeyson

Ever since Loki had come back from Asgard, he had been getting progressively colder; not emotionally but physically. Whenever you argued him, his Jotun form came out but this time, it wasn't going away. You were in the middle of an argument and he was becoming madder and madder. His skin turned blue and markings appeared across it and his eyes turned red. Loki lost his temper with you and the close proximity he was to you made it feel like you were wearing a swimsuit in Antarctica. He grabbed your arms and your skin turned black as if it was frostbitten. Pain shot through both your arms.

*

You woke up feeling cold and were shivering violently. You turned over to see that Loki had stolen all the covers. You smiled a little and pulled the covers back to you. You snuggled into Loki's side, feeling a little warmer. Although his skin was slightly cooler than the average person, it was still warmer than being on the other side of the bed. You thought about your dream and wondered if Loki would really use his Jotun form like that. For a while you just kept thinking until you finally fell back asleep.

...

Wanda Maximoff/ Scarlet Witch*

You came home from work and couldn't wait to see Wanda.

"Baby? I'm home!" you called. Strange; Wanda usually came to great you at the door.

"Wanda?" you called again. You walked into the kitchen and found a note from Wanda.

Y/N,

I love you but I can't keep doing this anymore. I can't take all this hatred, I can't take not being able to control my powers, I just can't take it. I don't to keep living like this anymore. I'm sorry.

What did she mean? Was she leaving you? Or did it mean that she... You frantically started searching to house. When you entered the bathroom, that's where you found her... dead in the bathtub.

*

"Y/N, please wake up," Wanda begged. Your eyes snapped open and you started sobbing hysterically. Wanda held you and spoke to you soothingly.

"It's okay, Y/N. I promise you that I would never do that to you."

"Y-you know... what my n-nightmare... was about?" you hiccoughed.

"I could feel that you were in distress so I looked into your dreams. I know that I shouldn't have done that but..." You cut her off with a kiss.

"I love you Wanda. So, much. I can't imagine my life without you." Wanda teared up a little and kissed you.

"I love you too, Y/N." You just lay there holding each other until you fell back asleep.

...

Bruce Banner/ Hulk

Bruce had been a little off lately. He hardly communicated with you anymore and he spent all his time locked up in the lab. When he went away on a mission, he never even called you. When Bruce was due to come back, you waited patiently for him to come out of the jet. Everyone filed out, except for Bruce. You asked them all what happened but none of them would even look at you.

"Y/N." You turned around to see Natasha.

"Nat! Please tell me he's still coming." Nat gave you a sad look and put something in your hand. You looked to see it was Bruce's wedding ring.

"I'm sorry, Y/N. He said he couldn't deal with this anymore and he went totally off grid. He said that you should just move on with your life." This... this couldn't be happening. Bruce wouldn't leave you like that... would he?

*

You opened your eyes to find yourself looking at the ceiling. You turned on your side to see Bruce still sleeping next to you. You reached out and took his hand, placing a kiss on the band around his finger. Feeling your light touch woke Bruce.

"Y/N? You alright?" he asked groggily.

"Yeah. Just a silly dream," you replied. He smiled warmly and pulled you close to him.

"Bruce?"

"Yes, Y/N?"

"Promise that if you have a problem, you'll talk to me about it." Bruce kissed you sweetly.

"I'll try."

...

Peter Parker/ Spider-Man

You were helping Peter with his latest project. Recently, he had been doing some work with something called 'symbiotes'. It really was quite fascinating work. Peter told you to monitor the symbiotes while he worked on a chemical formula. You were watching them under the microscope when then started escaping out of the Petri dish.

"Um, Peter? Are they meant to do that?" He looked over and his eyes widened.

"We need to get out of here!" He took your hand and started running towards the lab door. Peter pushed you out the door, slammed it shut and locked it.

"Peter? Peter, what are you doing!?" you called, slamming your fist on the door. The symbiotes started taking over Peter's body and he tried to peel them off.

"Y/N, I had this theory that they needed a host... I couldn't... let it be you..." he grunted. You could only helplessly watch through the window as the black substance took him over. He tried to fight it, but it was useless. He fell to the floor and stopped moving.

"Peter?" He snapped his head up and instead of seeing Peter's face, you saw a horrifying monster.

*

You opened your eyes to see that you were still in your own bedroom. You knew that it was late, but you just had to talk you Peter so you called him up.

"Hello?"

"Pete? I know it's late and I'm sorry if I woke you, but I just needed to talk to you."

"It's okay; I was up studying anyway. What's up?" You told him about your nightmare and he assured you that this new project was going to be alright. You spoke for a little while longer until you both felt tired enough to go to sleep and hung up the phone.
