So I became lucid spontaneously, and I was in my house. I wanted to try to fly. However, my ceiling was too low, so I wanted to jump out of the window and see if I could levitate. However, when I had the window opened, I became scared that my sleeping body might actually be sleepwalking and about to jump out the window, killing me. I was then too scared, so I decided not to jump. This is odd, considering I know that sleep paralysis exists and that you can't hurt yourself in a dream.
