Help finding a movie

[Mad Melvin]

Ok, im going to borrow this thread.

There was this movie I saw when I was 13 or something. I really don't remember much about it, except that it was a psychological thriller/horror. I think.
I only remember one scene from it. The story takes place in an old apartment building very similar to the building in Silent Hill 4. The main character was looking through a window and on the opposite side of the building there was this man/creature on a window and he/she/it was taking these dirty bandages from around his/hers/its head.

And thats pretty much it. I thought for a long time that the movie was Rosemarys Baby, but it wasnt. I hope someone can help me with this, 'cause I remember that it was a creepy movie.
