So I've been interested in Lucid Dreaming for a while. But I just started reading a book I bought last night. I read that just reading about it and being interested in it can give you an experience that night. And it did...I believe. Here's what happened.

I was dreaming normally...I was in a store arguing with my girlfriend. And all of a sudden I say to myself "I'm dreaming!" and I feel awake in the dream. But I wasn't in the store anymore. I don't know where I was. Just somewhere random and colorful. And then all of a sudden, for some reason, I imagine sex, everything goes black, I feel like I was doing that for half a second, and I half wake up, but quickly fall asleep. No more lucid dream.

It was weird. Since from when the Lucid dream started, my whole body felt really numb; similar to when you sit on your leg a long time, and your leg falls asleep.

Any suggestions?
