I have and idea and 8m sorry that this is so long I just wanted to give more details as to make it easier for you. :)
Y/N is a daredevil and decides to go explore this big empty house and spend the night. The house sits in the middle of the woods, away from alot of other buildings, falling apart but still stable enough to be in, that was abandoned decades ago for whatever reason. They won't listen to they're friends, they have they're mind made up.
Y/N's friend: Y/N please don't go in there, you don't know what's in there, no one's been in there in decades and you could get hurt
Y/N's friend: please, just don't go
Y/N: if your so worried then why don't you come with me?
They decide to go spend the night and leave the next morning.. They go to the house around the late after noon so they can scope it out and find a room safe enough to stay in. Soon enough night beings to fall and they're walking around near the room they're staying in so they don't get lost. They're walking through the house just looking around, but they can't get rid of the feeling that someone is watching them.
Meanwhile, shadow ethan is just chilling when some random person walks into his house. He follows them around for awhile and decides they aren't any threat, just some person who decided they wanted to go explore a haunted house. Kinda annoying but he's bored so he might as well have some fun
YES I will put this in my idea box but count on getting this eventuall because I absolutely LO V E-
