Dear Heyson, I'm not trying to do an advertisement, but since you have brought up the subject, I thought you might want to know that there is such a thing called paramemory. It is a device created by the Japanese people and recommended by Prof. Makoto Shichida,an expert in right brain stuff.It's sort of like a walkie talkie just with a pair of earphone and it is supposed to be able to bring the listener to alpha or theta state, depending on frequency of sound the listener tuned to.
