Ghost in the walls

They all call me crazy, mad, insane.. they don't understand anything. Sitting in this dark, isolated room by myself, being watched by a woman who reeks of alcohol.
No one understands what it is like staying in this room. It's like being left in a dark forest, waiting for death to greet me. They all think i can't do anything if I'm locked up, but they don't know..I'm the ghost in the walls. No one can stop me, no one can contain me, no one can touch me.
Every time someone walks in my isolated kingdom, I want to hurt them, make them feel my pain and sufferings.
Brother is coming. I heard them talking about it. I don't want him to come. He doesn't understand anything about me. He thinks he knows whats wrong with me, he wants to change me, he wants to fix me. Nothings wrong with me, nothing at all.

He's walking up the stairs, I can hear him through the walls. I can hear every single step he takes, like a lioness listening and watching her prey. I'm going to stab him, he needs to know pain, he's going to bleed.
