That's pretty cool... I'm not sure if it was something to do with stress or anything, but must of been fun
I'm a little hazy on the details though. From memory you said you just randomly floated up pretty much?
While my body floated a bit above the chair, my soul traveled astrally... (i believe) and was whisked at a quicksilver pace,(?speed of light) away from that vessel to see the two galaxies, that event was most instantaneous.
I was there for such a short time observing that view, than I was returned to the body which was now solidly upon the chair but looking forward and to my left I saw the third position of my spirit, with GK, upon the rug in the transparent rainbow which was the " teleporter".
Hope that helps a bit, I have had many odd experiences like this one so I was just amused and happy about this particularly nice one.
Many included arguments, with spirits appearing to be demonic, of which I was never very afraid, somehow. (I argued with them incessently at times, with theories of lifes flow...and mans essence, and such. What we were meant to evolve into. And that of course they should get into the light....for it appeared to be a superior place to hang out.
I still have a fearlessness to these things that I don't always understand.
Thanks for asking, and my theory is that YES, because of countless, stressors I developed (in response) certain abilities ~ which are considered esoteric ~therefore it is hard to discover the levels on which i was working...again, this is why I came here to explore ideas on these hypothesis.
