Hyperventilating leads to hallucinations instead of stimulation.
With me, hyperventilation leads to just a woozy/l'm-gonna-faint feeling.
As an aside, if you hyperventilate for several minutes, you then can stop breathing for a surprisingly long time. You just go around your daily routine -- and not breathe. It's a weird experience :-/
Yes, I learned that from no-equipment divers. With this simple trick people can look around down there with just a mask and fin. They claim with practice the mental effect disappears.
This thread is for:
- Perfectly natural and functional ideas that came from a spiritual, religious, occultist, parapsychologist etc. source (perhaps with some "baggage")
- Techniques that are bit difficult to explain and may be seen by the gullible as magic, but they actually seem to do something, even if that something is just a novel way to trick the brain.
Both things that are actually useful and "stage tricks" are accepted in this thread.
