So you want to go where no man has gone before? Down the dark lagoon past the galaxy or in the bed of others? Many people have equated this as Astral projection (esotericism) to describe a willful out-of-body experience (OBE), a supposed form of communication between minds by some me means other than sensory perception. It involves a manipulation of your soul that forms an "astral body" that separates from your physical soul that travel outside of the universe with the silver cord still attached.

“We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.” 

2 Corinthians 5:8 KJV

The concept of astral travel through projection is rooted in esotericism, satanism, and occultism and was promoted by 19th-century Theosophists—philosophers who explored the mystical and preternatural origins of the natural world. Is it a demonic form of explore or a license to have your way with someone you barely know? It is sometimes reported in association with dreams, visions, yoga, and forms of meditation.  Astral projection is commonly induced through various hallucinogenic, drugs, porn, sex, meditation and hypnosis.

Anton LaVey, the founder of the Satanic Bible, often was quoted as saying he travels a lot through this and had sex with many women that he desired by this.

There is no scientific evidence that there is a consciousness or soul the separates to go into the astral realm. Our soul created by the Most High, when absent from the body is present with the celestial realm.  Claims of scientific evidence of astral projection are pseudoscientific. When in fact, astral projection, could be associated with familiar spirits, that make you think you are leaving the body and visiting other places. Things are not always as they appear to be, wake up! Some things are not to be explored.
