I've been tinkering (when I have time) to see if possible to enter a lucid dream while emersed in a Ganzfeld environment. This is simply supplied by a mind machine, now the pules is in the GAMA range (which is quite deep) and they don't think dream imagery occurs at that level (thats if you brainwaves are truly set at this level by the machine). The Ganzfeld is typically a solid wall of light (some use ping pong balls covering their eyes) again mine is suppiled by the light googles. So I was on the GAMA setting and what I started to notice was Hypnogogic Imagery would easily take over the bright wall of light. It was like for a few seconds it wasnt there. Now I never fell asleep but to me that possibly gives the option of being able to dream (and Lucid if possible) from this state. It happend several times which was really cool. I'm going to try it later in the morning.

If anyone else has messed with Ganzfeld testing please post here, I'm very curious!
Thanks!
