Hi, I found this image very intriguing while watching youtube videos. I believe it represents altered states of consciousness that one can visit.

for me:
stage 1, cev, fractal imagery, fancy/moving checker board patterns, tone/ringing.
stage 2, open eyes looking back at me, entities folding in and out of the fractal images, beep-boop sounds.
stage 3, the vortex/tunnel, rushing sensation, relive past events, seeing myself outside my body.
stage 4, being someplace else, outside the body, other entities are present and interact with you.

If anyone is up to the task I think this would be neat in color with current images.
