I have gone through this video several times, and I’m going to be honest, I don’t believe this works. I only wake up more tired and exhausted after a short 20 min nap. I’m extremely skeptical of these by binaural noises after testing it for myself multiple times. Who actually thinks these work?
Be sure to check out the companion educational video, everybody has their own preferred nap length. It might be that 20 minutes is too short for you. I don't think your situation has anything to do with binaural beats, if you are in fact still falling asleep.
