Well, for me the lucid dreams are really fun but they don't seem as real a a normal dream. No dream is real but your brain thinks it is until you wake up. When I was 3 or 4 Some times I would try and run away from something and I suddenly could not run. My thought is: In a lucid dream...you aren't as deep in a dream, because you can control (somewhat) the dream. Now in a dream when I fall off a cliff, before I hit the ground I think **** this! Its a dream I can't get hurt and I just hit the ground and get right back up. When you start making decisions in a dream, your dream doesn't seem as real or deep. (In fact usually I wake up soon after a dream becomes lucid) Its fun though. I've been invisible, I could fly, I've been able to run at 100mph their really fun. Really you're not fully in control but just guiding the dream.
