I might have gotten a ghost in my room?

So this night I had a nightmare about a girl. She had severely dry lips, and in general I remember her dying and looking like a rotten corpse.

And that same night, I woke up, then when i went back to sleep I felt someone push me..It was too real to not be true.

Funny thing is, that girl was in my bed in the dream. It looked exactly like my room in there.

But I feel pretty comfortable and chill with the ghost, so might as well get some connection with her. She seems chill too; maybe she tried to wake me up to school.
