I read a book on the Tomatis effect once and was fascinated. If I remember right, the need for sleep is greatly reduced after 100 hours of listening to specially prepared Tomatis tapes. I wasn't aware that the Silent Subliminals are prepared to produce this same effect using UHF. I have two of these tapes that are voices only, no environmental sounds.

Combining silent subliminals with Paraliminals is a very intriguing idea. Auditorily, at least, they would compliment each other.
