I use brainwave entrainment, but I haven't tried this BMV version. All I have is a preset that bounces from 4 hz to 6 hz or so, but mostly stays between 5 and 6. This is apparently the state that's supposed to correspond to REM sleep. I use the portable meditation engine on the PSP because it's small and I can keep it near my bed with the screen off so I don't brighten up the room. |
