In an abandoned hospital

I'm in an old abandoned hospital that some people are squatting in. Some friends are with me. We enter the second floor and I'm alone in an apartment full of lush fabric. I curl up with a blanket to take a nap. The residents come home, and I apologize and leave.

I'm in a difficult to navigate stairwell. I make it to the second floor. I go into a room where a musician acquaintance lives, he has it set up really great. We're out on a balcony where I find an old violin-like instrument. It has two "strings" which are flat pieces of plastic. I find it quite easy to play and enjoy what I'm playing, but my friend says I'm pretty horrible and makes me give the instrument to him. While we're chatting, it comes up that the second floor is dangerously haunted. Alarmed that my friends are still there, I rush to go warn them. The stairwell is even harder to navigate. When I get to the second floor, I can't find my friends.
