To lucid dream means that you dream, acknowledge that you're dreaming, and control the dream in any way you wish. (Some people have had lucid dreams where they are unable to control it, though, and they seem to be the most interesting of all.)
One way of trying to dream lucid dreams is getting a computer reminder. See, if you do a thing enough in real life, it transfers into your dreams. The computer reminder tells you things like, "Look at your hands," and, "Try to walk through a wall. In dreams you can walk through walls." So that transfers into your dreams (after a while) and you start trying the things in your dreams. So, if you try to walk through a wall in real life, you'll go nowhere. But in a dream, you'll go through, and therefore know you are dreaming.
The thing about looking at your hands: If you look at your hands in a dream, they'll seem far away and twisted.
Another thing you can do is look at a clock in your dream. If you're dreaming, the clock hands will be wildly spinning around, and therefore you will know you are dreaming.

So, back to my dream from last night.
Lately I've been watching a lot of Doctor Who series 5, and I sorta didn't want to wait until this morning to watch the next episode (episode 6), so my mind created what it thought it would be like. Only it was nothing like the real thing (I just watched it). See, instead of Rory and Amy in Venice (1580), it was me as Amy and then the Doctor (modern day (or whatever time it was, it wasn't 1580)). So, for some strange reason, the Doctor and I went out to dinner at an Irish place (still no idea why). The owner said they had it better in Ireland. Then we were in a hotel room, and it was the whole "saving the world" thing again. So, for some reason I had to crawl through a tube that was a duct-like thing. It had two openings (besides the entrance), and the Doctor told me to go for the one straight ahead, not the one leading downward. It was the whole, "Amy, if you open your eyes you'll die," thing again. For some reason, though, I just couldn't do it, and I was claustrophobic, so I think Dr. Song used the teleporter again.
I ended up in my own house, and neither of them were there.
This is the part that makes me feel like an idiot, a complete cowpog. So, I got home, and it was a Saturday morning. I went into the kitchen and saw my mom walk away from the dishpan that had soapy water in it. For some reason, in my dream world, I always think I'm the Avatar, and as I walked past the dishpan, I thought, I'm getting a bit rusty; I'll try some waterbending. So I tried, and panicked, because I couldn't do it. Then I remembered what I had said to Zuko (he was teaching me firebending) in another of my dreams, "It can only be done in dreams." So I started doing all the tests. I looked at my hands. They look a bit far away, and they're not distorted, I thought. I don't think I'm dreaming, but I'll try other tests. I had forgotten the walk-through-walls one, so I tried the clock one, and didn't see anything abnormal.
"I'm not dreaming," I told myself, and looked out the window. The streets were piled high with snow. "Whoa, what happened?" I asked the universe, and got no answer except someone from our church mouthing something to me.
I can't remember what it was that she mouthed, but I grabbed my giant muave coat and some boots, put them on, and went outside. I saw Ben Dalling wrestling playfully with a little kiddy, and went to look for Lizzy. The street was covered with people in snow clothing, and I never found her.
Appenix (in other words, Extras): In the dream, the Dallings lived across the street from us, and I had generally accepted it as a fact. Also, I told my sister of this dream, and she said, "There's no hope for you."
I laugh at this dream because I failed to recognize it as lucid. That's also why I kept calling myself so stupid and idiotic and a cowpog. HOW COULD I HAVE MISSED IT?!?!?!?!?!!!?!?!
