But, he is a bit contrary ;)
I did get some wireless headphones so I can listen and he doesn't have to. I sleep better (unless the pain is REALLY bad) and noticed the REM sleep cycles changed a bit. More of them, for starters,which I assume means I am spending more time in DEEP sleep too. Dreams more vivid, like when I was younger. Always a lucid dreamer, I notice subtle changes in the tone/mood/'color' of dreams when I use the CD.
About half the time, I wear the wireless earphones to sleep. Yeah, probably giving myself brain cancer, but at my age, decent sleep and some respite from nagging pain is a fair trade off. Many nights, I take the phones off sometime during the night. If the dog (he is massive) gets restless during the night, I will hold the phones near him and he settles down in a hurry. Havocdad is a light sleeper, so if me & the 90 Pound Hound sleep better, he does too. Win/Win
The Awakening Mind CD is less weird to listen to. Lengthier musical phrases and more identifiable sounds, like birds, water, rain, thunder. It really works better than a couple cups of coffee and much gentler to the system too. I notice it revs up the cat, but that might just be the bird songs. The 90 Pound Hound, who is NOT a morning person, does seem to get moving better on the mornings I play that CD.
The sleep one has shorter, more nebulous, musical phrases under the tonal pulses, and hints of sounds, like I hear a bit of seagulls in there and a phrase that sounds like a derivative of a musical phrase from "The Beat Goes On". There are some chiming sounds here and there, like a big church pipe organ. It is really strange.
There is one for relaxation and one for meditation. Frankly, have not used either much. I really have lots of music I enjoy to relax; ditto meditation soundtracks. But I should use the meditation CD for a spell and see if it has an impact on that time like the sleep CD changed the dream content and quality.
Got the stuff at Amazon. Got the sleep CD first(
http://www.amazon.com/Delta-Sleep-System-Jeffrey-Thompson/dp/B000654YF6/ref=sr_1_2?ie=UTF8&s=music&qid=1240581603&sr=1-2) then got the 4 CD suite after a few weeks. Have to state, the sleep CD in the suite is different and I have not had the same results with it. Actually have more disturbing dreams with that one, so it does seem to have a real impact on what the brain works on when I listen.
With the dog and cat responding, I figure it is not all placebo effect. BUT, I do think our pets tend to have a telepathic link with us and it could be they are just picking up on the changes in MY head when I play the CD.
