I Have A Fear Of Falling Up

Into The Stars... For reasons I do not understand, I have an inconsistent and sometimes powerful fear of falling up into the sky. It is typically at night under an open and starry sky that I have this feeling that could be best described as the reversal of gravity. Sometimes, I feel that I would fall upward, but I would not continue out into space. There is some unknown destination before reaching space that is the source of my fear; less falling upward and more falling toward something. Other times, looking at stars triggers it. I get a sudden feeling that my body could, at any moment, no longer be drawn to the ground and I would fly up into space towards some distant star. I remember it occurring for the first time when I was under 10 years old. My father took me to see the 4th of July fireworks in downtown Indianapolis. On the way back, I wanted to sit in the bed of his truck, but I had to hide while we were downtown because it was technically illegal. As I looked up into the night sky, I felt compelled to look away because I thought that I would be pulled from the truck-bed into the sky. I forgot about this until only a few years ago when the feeling returned. Since then, it has been off and on throughout each year. It seems that it occurs almost always when I am physically alone. I have had at least one episode in which my girlfriend had to hold me because I was afraid I would fall up. I know I am not alone in this, and I felt it was as good a topic as any to initiate an experience. After all, I've put stranger things on here.
