It is better to be hypnotized by nature than by others. The sound of sea waves is the most natural hypnotic music, and its frequency is in perfect harmony with alpha waves. If not, go to the mountain and listen to the sound of the wind passing through the forest. If these conditions are not met, you can buy the corresponding CD or download it for free. You can search on the electric donkey.
Do not play hypnosis. God's creation only glimpses the doorway, which is too dangerous.
