OK so I'm a complete beginner at this. However, last night i finished reading a book called Lucid Dreaming by Charlie Morely (awesome book, highly recommended) and that very same night I found myself kneeling on a bed in a dark room and straight away I knew something wasn't right. I did a RC and sure enough my hand is massive and there are far too many fingers there!!! Now I know for sure its a dream and I'm trying my best to stay absolutely calm.I say out loud 'be cool, its a dream', and then I look at my hand again. Now my fingers have gone from being massive to tiny little stumps, which I find disturbing so I stop looking at it. Here's where it gets super weird.... I try to move but I can't. My body goes completely rigid and starts to jerk violently. I try to move my arms but they're stuck solid by my sides. Then I get these intense vibrations and a high pitched noise and then I'm awake!!! Racing heart beat,confused as hell.

My question is this: what the hell happened in there? Did that count as a Lucid dream? If so,why wasnt I able to take control??

Thanks
