OK, I had an experience last night that I'm hoping someone can explain to me....I'm pretty much a newbie to controlling my dreams, although I've had a few spontaneous events.

I woke at about 5am and in a dozy kind of dreamstate & decided to try some of the things I've been reading about. I have no idea if it was the right thing to do which is why I need advice. Anyway, I rolled on my back and was drifted off to sleep again while repeating the words 'I want a lucid dream' over and over in my head. I also fucussed on the pillow beneath my head, instead of what was going on inside my head.

What happened: within a few minutes I felt the strangest sensation in my arms and legs, and a brightness to my inner vision (not sure how to explain it). The weirdest thing was the feeling that someone had placed an enormous icepack on my head! Really. My skull felt....cold.

I started to worry and woke myself at that point and couldn't get back to sleep for a while.

What happened?!
