Why can I have HI when I'm awake?

Okay so ever since I was a small small child I have been able to experience what people describe as HI by putting my eyes in a dark place and closing them then looking at images on the back of my eyelids. When I first heard HI described, (patterns, shapes and colours on the back of your eyelids) I thought "WTF? I get that all the time :shock: " I dont know if this is normal or what. Come to think of it, it is easier to identify the HI when I'm drowsy, but I can also see it on my eyelids when I'm as awake and energetic as a chipmunk chugging vodka and redbull and throwing in some speed for extra fun.

If anyone else gets this too, or if you don't get this but know a bit about it can you explain this to me?

This is normal that happens to everyone when they close their eyes I wouldn't really call it HI

Thanks Mirui. That's what HI sounds like to me though, geometric patterns swirling and psychedelic colours :P

Hypnogogic images or sounds come one in the Theta brainwave stage of sleep. So, technically you are neither completely awake or asleep but rather in a form of self-hypnosis that we humans experience every night before falling asleep.
