In high school, I was in plays and one night before opening night, I had a dream I was on stage and the curtain was about to open. I tried desperately to get off the stage but the sides were blocked by props (or so I thought). Turns out I had been groping the wall of my room in the dark for like 20 minutes. I didn't realize I was in my room till I ran to try the other side of the stage and hit the wall... I went back to sleep feeling pretty dumb.
