Dream interpretation! Dreaming feels that the soul is out of its shell and floating in mid-air. You can see everything around you, and you can also see yourself lying in bed, the shadow of the moonlight on things.
This is a good phenomenon, but don't indulge in this realm, otherwise it will be dangerous. Because you lack protection and have no experience in the spiritual world (just like an ignorant child who comes to the world of flowers alone), it is easy to "recognize the illusion as true" and be deceived and used by evil spirits, and then both body and mind will be in trouble.
If you are a Buddhist, I suggest you read the Shurangama Sutra, especially about the 50 Yin demons and the Tathagata, which has a detailed analysis and description of your situation.
You can also believe in Jesus Christ, the bright and holy true God and Savior, and be protected and enlightened.
I sincerely wish you peace and health! ! !
