to discuss this issue I have to be very objective. I can not claim to astral travel really happen in the reality in which we live, since I have not collected enough evidence. On the other hand, I found very interesting facts. the mind is certainly extraordinary.
I can not give you a precise manual instructions how to do. for now only will share experiences made in that state. trying to establish a relationship that these have had with the reality that we all know. be patients.

The first time I thought to have a recognized body experience happened to my early youth. There were several nights that have some felt to be on top of me. I felt his weight, felt his whisper, not looking. A demonic presence so to speak. Helpless for not being able to move my body just pray I stay, what note to be affected, because this is such afflicted with every prayer.
An already sick of suffering repeatedly done, night decided to confront this entity. I did force the limit to move one of my arms and I settled finally achieved a coup against this being that resulted in a collision with some energy field so that the entity did not seem necessarily solid. After this I find myself sitting on my bed all alone and no threats were, but looking even better I saw was lying, but exactly my physical body. Afraid to believe that he could be dead decided to return to my body so I end up waking up.
Since then the threat did not reappear, but the state of bodily paralysis is very often kept repeating to EXCEPTIONS that my arms were no longer imprisoned, could move up today. That's when I decided to inquire about astral travel and split to end realizing that even as a child he had had experiences unknowingly.

I have had countless experiences so possibly not be able to count them chronologically.
Today I can only build on that I suffer from sleep paralysis, but more than that he had learned to control it. Say to cause it at will. It is said that as a child i had experiences that can now claim to be product and hypnagogic imagery hypnagogic hallucinations. And do not say he saw ghosts and stuff, but the point is that all these experiences have nothing to envy to the same reality.

astral travel does indeed happen as you can project your consicousness to other plans of existence the astral world is 2 dimensions ahead of our current one, but there are higher astral planes to which we can travel some people can just stimulate vibrations and just phase themselves out of this reality and others merely learn to discipline their mind and achieve perfect control of it, there are many feats to our mind that even us with all our technology cannot find but yet the ancients knew each dark secrete it had, in todays world we know more about the ocean then we do about our mind, and we know more about space then we do about our oceans

much to not enter this site does. But leave pending to talk about certain experiences I had for years. the most common were to wake up and see something standing beside my bed. generally deformed or monstrous-looking beings. the particularity of these experiences was that visions had no movement, but were fixed.
Other experiences were those that were not fixed, and had movement although these were less frequent. the characteristic was operating in longer distances. I only remember two that I consider the most representative. one was at the post sleep. I saw a lady in the room adjoining ordering clothes apparently. never interact with this vision and the vision put any interest in me, what is striking. just watching from one moment to another vanished from my eyes.
the second is a man in a cloak and black galley approaching from a closet to my bed slowly disappearing within walking distance of it. This vision was presleep was very abrupt and how he. I had a clown doll hanging on the handle of the wardrobe and this takes the form of this entity. when the entity disappears a few steps from my bed the clown doll reappears again in the handle of the wardrobe. It was a terrifying experience as much memory. if you want to know how this spectrum look see the movie "The Babadook" the coincidence is incredible. sorry but the traaduction.
