The earliest experience that I can remember was when I was about 5/6 years old.
I had, as a child, an uncanny ability to look at an item or fixed point on the wall/floor and concentrate/focus, I even remember my vision getting darker and darker around the edges until it reached a small point probably like tunnel vision. I would do this completely voluntary and to the point where my mother would literally shake me to bring me round, I knew what she was doing but it felt like I was somewhere else. I suppose it was some sort of trance like state I was in. Now, I was completely aware of what was happening but while it was, the sounds around me would get faster and faster and faster until it was one continuous noise, all this probably only took a few minutes but felt a lot longer. It happened a few more times as I grew older but the last time I can remember I was about 10 or 11. As it started I realized what was happening and decided to let it continue but when the sound got to the point of almost one continuous noise I got scared and broke the concentration - It never happened again. I have since tried on numerous occasions but without great success, I can start out the same as before but seem to lose it after about a minute, maybe its blocked or my subconscious is blocking it.
Were these trances or was I projecting? I have often wondered what was actually going on. Has anybody else experienced this sort of thing?
