One time I had to have some dental surgery. When I went in to the doctor, they gave me some crazy strong medicine that made me pass out in ten seconds. The next thing I remember, I was sitting in a room, where my girlfriend told me that it was all over. I smiled and closed my eyes.
"This is awesome," I thought, and opened my eyes again. When I closed my eyes, I would immediately start dreaming. When I opened my eyes, it was back to reality. I tried to explain this to my girlfriend, but it came out more like:
"Watch! When I close my eyes, I hallucinate." And then I closed my eyes to show her.
