lucid dreaming is a bunch of hooey.
Eh. I've done it. Once. That was a weird night.
I had just started rehab and with drugs finally purged from my system, I was dreaming for the first time in maybe 4 years. The night it happened I dreamt I was walking home from work to the tent-city I was living in and it kinda clicked, "Wait...I don't live in Lubbock anymore. I don't walk home to my tent anymore. I'm dreaming."
I looked around and I was still dreaming. Not quite awake. It was SURREAL. I could feel the crunch of gravel under my feet. I smelled cold morning air, which was another weird thing cause I never got off work early in the morning like that. I did what I always loved to do in dreams---I lifted my arms up and flew. I went up over 19th street and over the mess of trees, apartments, and rent houses that was Tech ghetto. I actually ended up waking up THREE times that night, immediately falling back aleep and still knowing that I was dreaming. The first two times I was still in Lubbock. The last time, however, I was in an old child hood home. I was very surprised, and spent the remainder of my dream exploring my old back yard. I got very homesick and woke up.
I have never lucid dreamt that vividly ever sense.
