Thanks for your answers.
I tested one of the CDs yesterday, it was designed to archive a deep sleep (delta). Sounds interesting and I tried. Seems to work, I have a very intensive and long dream. So Delta stadion wasn`t archive because delta 0-4Hz shouldn`t produce dreams :-)However. Allready had have such intensive dreams before, but quite seldom. Will test it this night again, than I`m able to say more about.
Anyway, I just was so terrible tired from my working week, may this reason arhived my "deep" sleep. I will go forward using this cd over 2 Weeks and than I`m able to report more detailed results to you. If it really seem to work or not.
