I wanted to call this new chapter of my blog the Noncyclopedia, or Experienceclopedia (combining the words experiences and knowledge), to discuss a topic in the Wikipedia. As writers try to define the topic it is not a "a supposed form of telepathy" as mentioned in the Wikipedia. Telepathy may appear to become possible in the experience it is not, on the whole, a "form of telepathy". Astral projection is found in occultism and can be similar to lucid dreaming. The sense of astral projection may be experienced through hallucinations that may be brought on by medical operations or disorders as well.
While there may be no scientific evidence that the consciousness can separate from the body, the author Robert Monroe, collected much data from his astral projection experiences to write about it. His family, per info from his first book Journeys Out of the Body, believed that Monroe could project distances to perceive things going on his family's life without being physically present.
Monroe documented 3 realms of the astral world. The first one coincides with this world. Some travelers in the astral have been able to fly to points around the world or distant planets in space. The second realm appears to not be subject to time. Multiple times exist at the same time in this area. The third realm is some kind of parallel world that is similar to our world, but it has different features or technology than our own.
I myself underwent a contract with a witch years ago. I paid for an astral travel course for $45 which was supposed to help me project from my physical body. I was successful but the experience made me sick for the remainder of that day. I later used numerous books on astral projection to escape my body temporarily. I never was able to escape on a regular basis. It appears it is a skill that people are good at or only have the experiences temporarily.
There are a lot of books on the subject. However, I find that these books are the true classics and were in my collection at one time.
