So this is the dream i had last night

Mentions of sexual assault

The dream featured Eren Jaeger and a few of my friends from one of my classes. So not close friends just friends. Anyway, we were at my house having a sleepover and we decided to play hide and seek because immaturity and boredom. I don't know who was counting because it wasn't my POV, it was overview but I was there. However, instead of going to my hiding spot, my brain travelled to Eren who had hid in my bed under the covers. This is the part where it gets weird. So, then one of my friends goes into the room quietly and then pulls the sheet off him. He thinks he was caught but then is greeted by my friend straddling his waist. Eren then gets confused at her action. She then leans to Eren's ear and tells him “We're all alone we can do what we like. ” Eren then starts to try and tell her no quietly and in a state of flustered fear but feels like he can't because it's his friend and he doesn't want to make it awkward. She then starts rubbing his nipples through his top and he starts to be a bit tearful and tells her to stop quietly again. Fortunately I walk in and see the situation but decide to ignore it. No I don't leave, I tell them to come downstairs because we're about to do something. Idk what. The next day in the dream shows my friend apologizing for what they did and Eren says okay. Later on i have a one on one conversation with Eren and he tells me what happened and that he doesn't know if it was wrong. I tell him it was sexual harassment but then woke up because it scared me.

So why did I have this dream?
Was it to show me what that person was really like?
Some de ja vu shit? Psychic?

I don't know but if someone can help me out that would be appreciated. I really want to know.
