Well it plays binural sounds of something and stimulates the brain and has certain effects. I know this program is old, but I thought it would be cool to speak about which ones you have tried.
Ok so I tried the lucid dream one last night. Now I think I already am in control of my dreams, but I can remember a lot of my dream, as it said I would, and this is 3 hours after, and you are supposed to forget your dreams in 10 minutes.
So, what experiences have you had? If any.
