Well this actually happened quite a long time ago. I was in a dream, and suddenly realized that I was indeed dreaming. I read about the spinning technique here, that you could spin and shout where you wanted to be and you would end up there. I started spinning and was yelling at the top of my lungs "HALLOWEENTOWN, HALLOWEENTOWN!" (From the Nightmare Before Christmas, a movie that I know like the back of my hand) But my head started to hurt and everything turned black so quickly there was nothing I could do about it. I woke up with a POUNDING headache (which I hardly ever get).. I found it weird how the spinning in my dream affected the real life, because I woke up dizzy with a headache.

Has anything similar happened to you?
