Second? Going into hypnosis is actually like falling asleep, right? Hypnotized? It's like a long dream, very real and unforgettable.
So don't listen to personal advice if it's okay. It may not suit you. I have several MP3 formats for you to listen to. You'd better fall asleep after listening. Don't loop the single once. Listen before you go to bed. I think the effect is very energetic? I slept for six hours and wanted to sleep for ten hours. The sound should not be too loud or too small.
