I was watching Paranormal State and they mentioned the Ganzfeld Experiment which can be done in anyones home easily. Here is a quote from a Psychology Journal. I am very curious if anyone here on the Nexus has experimented with this, and if they have what was it like. Apparently it can produce some very intense hallucinations..
"The
Ganzfeld Procedure exposes the participant to ‘unstructured’ sensations usually by placing half ping-pong balls over the eyes so they can only see diffuse white light and by playing white noise through headphones.
It is probably best known for its uses in parapsychology experiments, but it is also used to induce hallucinations and sensory distortions which are much more likely to occur in the absence of clearly defined sensory experiences.
A haulluciantion description:
In the right side of the visual field, a manikin suddenly appeared. He was all in black, had a long narrow head, fairly broad shoulders, very long arms and a relatively small trunk…. He approached me, stretching out his hands, very long, very big, like a bowl, and he stayed so for a while, and then he went back to where he came from, slowly.”
Take a look at the link if your interested. Its short and describes the hallucinations.
