yes, Hamster,,, CenterPointe specifically includes a Sleep CD with their set... but i believe you can buy it seperately,,, it does not require headphones to use, and can be set to repeat all nite, if you need that... i can tell you that it DOES work~! i usually listen to it at the end of my session, to let me remain in the calm state longer.

thanks for asking~ these holosync CD's are sometimes referred to as "Alpha/Theta entrainment" by psychiatrists, because they cause the brain to move toward and eventually harmonize with the particular brain wave format on the disk. this has the effect of changing the brain's performance perameters.... or causing it to become calm, feel more composed, etc... while encouraging the brain to make those connections required to maintain that state.

many people fall asleep listening to the regular CD's, because it makes the brain work to make those new neural connections, or repair the damaged ones. the instructions say, "don't go on to the next level until you stop falling asleep on this one". that of course does not apply to the Sleep CD ~

i hope you find it helpful
best wishes~
