This soundtrack is great for dream recall and lucid dreaming during the night. This program is in the theta region of brainwave activity with interruptions of faster alpha. The pattern assists the listener to experience lucidity during the REM cycles of sleep. Also uses white powder of gold for bliss and white light as a strong carrier wave. The carrier wave will amplify your intention for lucidity! Headphones optional. With version 4 we have refined and made the technology more powerful by strengthening the carrier wave of white light, as well as the other harmonics of beneficial frequencies such as higher harmonic of gold, positive green, etc.
