Bad trip

Calmly, I open my eyes. The room is white. No furniture. No windows. The light comes from nowhere. My mind is blank. I breathe deeply. I am lying on the floor and I feel nothing. Am I dead? Is this heaven? I sit. I see a door. I stand up. Every step I take makes the door go farther. I stop. Turn around. I see a wall. I walk towards it. It goes away. Maybe I'll never reach it. I sit back. Maybe it's just a dream. I lie on the floor. The door is behind me. I grin. Stand up. A green garden reveals itself as the door opens. I remember everything. Every single damn thing just seems to fit. All the little details. I want to wake up. I can't. I'm trapped on my own fucking mind.
