Extend the Story - Add a Room

I should try, I have nothing to lose... But I need to be realist instead of candid! It's impossible that someone appears to help me. I am in reality, not in a random story written by a 17 years old girl.
"I know who you are and I want to help you! I understand if you don't trust in me, but I found a little piece of paper in the asylum director's room" An unknown nurse whispered to me. "If you solve the riddle on this piece of paper, you will access to other clues to find the code number of the asylum electronic gate ..."

This is what is written on the paper:
9086951907
