I have bought a fantastic book on Lucid Dreaming by LaBurge..Lots of information and individual accounts, it helps to know your not the only one!
Leaving my body or just dreaming? Its hard to say for sure, and I guess, if I knew I was it would change my outlook on life completely! Im 32 and have never been a religious or spiritual or person. But I think that may be changing :O

Often I will wake up in the night, go to the kitchen to get a drink, then notice the clock is spinning fast, or I go to switch the light on and my finger goes through the wall..and even on a few occations I will go back to bed, unaware Im dreaming, and see myself sleeping.. LaBurge describes this in his book as false awakenings..

I also get a shapeshifting owl on my bedroom window cill, I then know im dreaming, and litrally roll out of my body.. This is the same owl that led me to the golden pyramids...

Haha, its good to get it off my chest, family and friends would just think me a dream bore, or worse, barmy! Thank you for taking the time to read my post too..
