During the past couple of weeks, I've systematically experimented with something I've found out a few years ago by accident. Back then, I was listening to a very calm trance track on my bed. I set the cd-player to repeat that single song endlessly. Then I fell asleep, and about 10 hours later (the track was played all the time), I felt incredibly calm like never before in my life. And I stayed that way throughout the entire day! So, during the past weeks, I've had quite a lot of work to do, and since the days became more hectic, I remembered above described effect. So, I decided to experiment with different music. I've specifically used some Indian classical music and very calm ambient sounds (sounds of nature). The results were amazing: after a whole night with rather fast Indian sounds, I felt quite confused on a subconscious level for the entire day. But after I experimented with ambient music, the next day I felt like many noisy voices from my subcionscious mind totally disappeared. Llike an incredibly calm and rational machine! It's very hard to describe the effect - I've smoked pot regularly a few years ago, and although the effect is totally contrary, I can state that the extent of the change upon the conscious mind is similarly strong. I basically feel like a calm magnifying glass for an entire day after a night with ambient. I've never read about this anywhere else, so I decided to post it here. Cheers! Edit: The ambient tracks I'm referring to are from David Miles Huber, from his series "relaxation & meditation with music & nature"
