I posted this on another board, but only one person replied and they didn't know the answer. I'd like to see what you guys have to say about this:

I've noticed, if I am dreaming in a certain position , and I half wake up, and switch positions, sometiems I have the HARDEST time picturing that dream. I just simply cant make a clear mental picture of it. Then I switch back to the original position, and it works, I start to dream it again.

This is odd, and I've noticed it in situations where I'm awake as well. Many times have I been sitting, thinking about something for a long period of time. Let's say one example, where I was on a road trip. I'm not sure what I was imagining, but that's not important. My head was tilted to the side, and my eyes were opened. I was like this, thinking, for about 10 minutes. My neck started to cramp so I tilted it the other way and tried to continue thinking. It simply didn't work, or if I did manage, the mental image wasn't as clear. I switched my head back to the original angle, and I could picture what I had been thinking about quite clearly. I also noticed, if I looked at the object I had been staring at for a long time while I was originally thinking, then I would also be able to create a much clearer mental image.

I think it's pretty much the same thing... asleep and awake, and has to do with, not so much the position of your whole body, but the position of your head, and your eyes. I'm pretty sure most of you have experienced it before... Why does this happen (if anyone here knows a lot about how the brain works)?

Cheers,
