Enjoy 8 hrs of Super Deep Sleep, Dark Screen, Delta Wave, Healing Music (no piano). This track is specially mixed to help you relax and fall asleep fast. The darker screen keeps your room from being so bright and interrupting your sleep. It's been scientifically shown that sleeping puppies help you fall asleep faster and longer. ;) ~Peace Another Deep Sleep Delta wave video over here: https://youtu.be/X_D3aKeTj_A
