Have you ever heard of/had lucid dreams ? I thought I was crazy and nobody believed me but I had one once. It was the best dream ever he he. I remember that I realized it was a dream and then could fly all over the place. I could even choose if I wanted to wake up or not.
I been reading about it and it seems that you can control it and there even are techniques to achieve it. ( http://www.lucidity.com/ )
So, how about you ? Have you ever had them ?
