I'm still unconvinced of lucid dreams' possibility. Even if you subscribe to the psychodynamic approach (dreams are meaningful representations of suppressed feelings) and not the cognitive approach (dreams are random firings of neurons in the frontal cortex), you'd still need a tangible amount of consciousness while sleeping. This would amount to daydreaming, NOT REM dreams. When you are engaged in REM sleep, you are UNCONSCIOUS -- you cannot make conscious decisions. Though it seems that you can in your dream, I have a very hard time believing that you actually can. Is it so unfeasible that you are simply dreaming that you have conscious control of your dream? How do you know it's real if it happened while you weren't conscious?
The other possibility is that you are daydreaming -- that is, you're just in a very relaxed state of consciousness, where vivid imagination is often mistaken for dreams.
Basically, what you are arguing for requires that you be simultaneously awake and dreaming, and given that you have your most vivid dreams during REM sleep, it's not likely that you're conscious.
