The Dream Magic Experiment

I was in my room. Or at least a room. I was half-kneeling on the floor, as if I just dropped down from somewhere. I knew I was dreaming. I decided to go through the window, but it stopped me. I punched through it and the window panes broke down, but behind it, there's concrete and bricks. I can't escape.

NOTES:

I didn't feel desparate, just frustrated that I can't get anywhere in the dream, despite knowing that I'm dreaming.
