there have been a few occasions when I slipped into a lucid state while dreaming. it has always been accidental, and I usually end up waking up as soon as I realize what is happening. on another note the paralysis that the body undergoes during sleep has often affected me in dreams. I never knew what it was until recently when I did some research to figure out why I punch my fiancé when I sleep. turns out that sometimes the paralysis doesn't work, and you end up flailing about in your sleep. back to the point, during dreams with a lot of intense emotion the paralysis of my sleeping body bleeds over into my dreams, and suddenly no matter how hard I try, I can't talk, (usually in the dream I am furiously yelling at someone) and I can't run, or fight. where usually I am chasing someone, running from someone, or fighting someone for my life. it hits me suddenly in the dream, as though every muscle in my body was instantly replaced with lead.
