Ganzfeld effect

Basically, you are able to gently bring on a lucid dream without falling asleep. Take a pingpong ball and cut it in half. Place these two halves over your eyes, tape then down using medical tape (it won't cause chaffing). then you get 60 mins of white noise and a red light. Position the light so that you are looking directly into it while you lay down. Start the white noise and just lay there... and wait...
