Something strange

[Diana]

You may be experiencing the vibrations that precede astral projection.  As you go into sleep, your astral body unfocuses or detaches from the physical body.  It's on a faster vibrating frequency than the physical body, so during the separation, depending how long it takes you will perceive the vibrational relativity between the physical vibratory rate, and the faster astral vibratory rate.  This happens to all people every time they go to sleep, but usually we are not conscious of it.  And once your consciousness has fully withdrawn into the astral plane, you don't feel the vibrations anymore, because you are no longer perceiving seeing both at the same time.  If you practice consciously entering into the sleep state, as you enter into sleep paralysis you will begin to feel the vibrations starting.  Not everybody experiences this symptom however, which I suspect is due to a rapid transition into the astral.

Anagogy is correct from my experience. I have experienced this myself exactly, along with the feeling of a low-grade terror (as when it first happened I was only 15 and I had no idea what was going on). I went out of my body (the terror feeling disappeared at this point) and "floated" out to the living room where my mother had fallen asleep on the sofa and my father was reading. I could not get the attention of either so I "flew" out the big window into the night sky, which is when I had the thought that that wasn't possible and I was immediately back in my body. This was a conscious experience, and not imagined in any sense. I had not been asleep. just entered into that in-between state as anagogy describes.
