(I got this idea while I was dreaming, four of these ideas were from my dream, one just came up now because in a role-play someone requested angst happen)

Scenario one:

A is a young but brave ghost hunter, and they decided to enter a very haunted house, b happened to be the spirit in the house, while A was in front of a mirror, he said " is anyone here?" Resulting in B deciding to get a bit mischievous, revealing himself and pinning A against the mirror ( this is literally the only one I saw a smut moment happening in, but it doesn't have to be smut)

Scenario two:
A had recently lost their best friend/crush B to a car accident, and decided to try and talk to him with a Ouija board, and some ghost hunting technology he borrowed from his father, he walked around the abandoned house his parents once lived in and started calling out, eventually placing the Ouija board and candles on the dining room table, lighting the candles i'm breaking an important role of the Ouija board, never do it alone.

Scenario three:

A and b we're ghost hunters, and they decided to do a dangerous mission, searching for a paranormal spirit in The abandoned asylum in their town, they manage to come in contact with several spirits, The kindest of which happened to be a 21 year old looking man, c. C warned the two to get out while they still could

Scenario four:

B and A had known each other for a while, then, A had died, resulting in b being desperate to try and find him again, he joined the group of ghost hunters just to try and find his friend, The group of ghost hunters eventually found A as a poltergeist, sitting in his room not talking

Scenario five:
(I realize at this point I should warn you that suicide will be inevitable in the role-play... so trigger warning of blood, death, and suicide)

A Had recently died in his home, as a burglar had broken in and killed him, his boyfriend b have been the first defying out of his boyfriend's death and just hugged A's Cold body, three years later b had a noose ready in his closet, he walked over to it, not realizing his boyfriends spirit was trying to stop him, even holding him back with a hug, confusing b, as neither of them had believed in ghosts at the time
