A while back, I had posted a description of an HI phenomenon along with some other related topics trying to get an explaination of what this is. Here's a cut/paste of the relevant section:

******************************
The other interesting effect I sometimes get in this state is hard to describe. Essentially, I get light
specs which collect above and between my eyes. When they collect into a bright orange ball they "fire"
toward me and disappear. This repeats in a time periodic fashion - about once every 6 seconds or so.
After 5-8 orange balls of light fired toward me, it usually disappears.

The only thing I ever found which seemed to describe this phenomenon is the notion of the pinneal and
pituitary glands sympothetically charging up and down (electrochemically) during certain mental states.

I see this during deep meditation on occasion. I also see this before falling asleep in the middle of the
night from time to time.

********************************

I have never heard anyone describe anything quite like this. I know various people believe in a "third eye" and certainly staring at a point above and between your eyes with eyes closed can lead to an effect of "seeing" a ball of white light. But what I describe above is much more than that.

What the hell is this exactly?
