Thanks much, but no thanks!
As a child somehow I developed an acute phobia to heights, to anything up or down.
I was terrified of going up the stairs and of getting on elevators, getting up on top of anything, like a ladder, I even felt dizzy just looking up the ceiling, when I was made to go up a building I was afraid to look down or even to get too close to the windows.
I would crawl to get up stairs.
It took me years to little by little get rid of most of that problem, I really forced myself.
I think that now I am no more afraid of hights than most people are.
But I might have a mental or otherwise block to astral travel, because on my tries years ago, I just could not do it anymore, I think that that first time scared me so much that it caused a very deep trauma.
No, I am not going to try again, sorry.
I now like best to try to sense things close to my hand and fingers, that might also have to do with memory and a very very good nervous control of the muscles, but there is also a little kind of sensing that seems to be not fully related to memory of the position of objets that I see while my eyes are open, things have to be close to the hand and fingers more or less, but not touching and I don't really feel them as when one touches something it is more like sensing, often have to pass the hands and fingers over close to the stuff several times, to better be sure if there is really something close there or not and even then I can't be too sure, just more or less sure, it is easy if I already know for sure that there is something there, like a chair close behind me but not touching me, then I can find and touch particular parts of it with my eyes closed and moving my hand behind me.
Same thing with a glass on a table in front of me, etc, it is probably often but not always a combination of memory, very good muscle and nervous control and extended tactile sensing or some other kind of sensing.
I have even been able to stick a drinking straw thru the open mouth of a soda bottle that was on a table some distance in fron tof me and I did it with my eyes closed, I have tried that a few times, started that with first learning how to find-sense the top of the soda bottle and also of being able to find- the end of pens and straws, Etc.
Well Good Luck!
