Are you even real?

(i hate trying to edit photos, i forgot how, if you know how to fix the cover photo PLEASE let me know for the love of god.)
Anyways, Y/n is a ghost, normally she hangs around with Wanda since she's the only one who has been able to see her, her ghost friend is Pietro, they all hang around Wanda. Wanda has almost been caught multiple times while talking to Pietro or y/n but the team pushes it off as not having enough sleep.
One night Y/n is with Pietro bugging Wanda when she gets pulled away, not physically obviously but something is pulling her in a certain direction. when she goes through a door she comes to a sleeping Natasha having a nightmare, what will happen?
