I seemed crazy last night. I beg your knowledgeable answers.

This is actually the phenomenon that the body is asleep, but the consciousness is not asleep. Without the bondage of the body, consciousness will move as it pleases, which becomes an out-of-body phenomenon.

If you are interested, you can prepare some necessary conditions to create this scene.

Prepare headphones, play single-frequency sound, and then relax, one posture at a time. If you keep relaxing like this, your body will suddenly have a feeling of shaking or vibrating, which comes from inside your body. Because of the monophonic sound, your consciousness is still awake. At this time, you should have fear and struggle, because you want to move your body but you can't. If you do this often and stop being afraid of this vibration, you will have what you call an out-of-body experience. Of course, what I said is just an example, and some people may have different views.

However, this OBE consciousness still belongs to the level of body consciousness (conscious consciousness), so this OBE consciousness will not last long before the body wakes up or goes directly to sleep.
