Um, I never paid any real thought to this. But for a few yrs. now, whenever I get up from laying down or even sitting down (in a relaxed position), my eyes completely black out. It's really random for how long they black out, sometimes it's only a few secs.; sometimes it's more than that. Even if I've laid down for only a couple of minutes, it nearly always happens.

I can remember a couple of instances in my life where it was for an extended period of time. Once, I wasn't feeling very well (had some kind of stomachache) and I felt like I was going to vomit. I was at the sink, but I couldn't vomit, just felt nausea. Well, my head was sort of bent down toward the sink, and when I lifted my head I blacked out. I remember going a bit crazy as I stayed blacked out, and running around for a few mins. (I was young, and panicked ) I went and laid down, then regained my vision slowly.

I remember looking this up online. I read somewhere it wasn't anything to be worried about and was related to low blood pressure. My parents said it wasn't anything to be worried about as well, but both sources aren't much reliable. Oh, and I can't go to a doctor or anything. (parents)

So yeah, is this normal? Something to be worried about?
