The act of hallucinating without the use of psychoactive drugs, such as LSD or acid. This requires one ping pong ball, a radio with headphone jack, and a red lightbulb. To hallucinate, cut the ping pong ball in half and tape halves over eyes. Then turn the radio to a white noise (static) station and put on headphones. Finally, stare into red lightbulb and wait for about half an hour. Soon, you will start to hallucinate.

Ben: I was at home, red-lighting. I rode a unicorn underwater.
Greg: That explains why you didn't text back.
