Query: Altered conciousness

True Story: I went to bed and put this CD on. The next day my roommate told me he had been standing in the kitchen and felt completely disoriented from this sound in his 'head'. It wasn't until he passed by my room that he realized the music was from my stereo. He thought he was having an acid flashback. That's the best way I can describe this sound - it's wonderful and relaxing - like a soundtrack to a space movie. Love it!
