Well, I KNOW I'm dreaming. I'm just a daydreaming kind of girl it seems...
(Are we having fun yet?)
Some interesting comments on this thread. My lucid dream experiences are mostly positive. A few not so good ones. However, I haven't trained myself to explore this "lucidity" factor as well as some others have. From what I've read it seems that as individuals we need to develop a system for "noticing" it, and then we will have more occurrences of that kind.
Many people use a repetition technique. They will ask themselves a question, "Am I dreaming?" or some such repetitious act during the day. This can go on for a long time before it gets into the subconscious mind. After a while it will appear in their dreams and be the cue for becoming lucid.
One person I read about carried a ball of paper in his pocket during the day for weeks. He checked it regularly during the day. Then, sure enough, he found himself doing it in his dream. But the paper wasn't in his pocket. There was the cue. Bingo--lucid.
It seems that people have to have an ongoing interest in lucidity for it to occur regularly. There needs to be an underlying motivation, doesn't there, for just about anything? And practice, of course.
As for the ultimate question, are we dreaming now?
I think so! Dreams happen. Don't they?
As for how to know when we're dead? Well, I suppose if you're in the habit of asking yourself that all the time you'll ask it wherever you are, won't you? What does it mean to you? I would guess that we are as alive as we think we are, wherever we end up in the end...
If I had 2-3 car crashes or incidences and didn't have a scratch I'd have a hard time believing I was alive too. Or maybe I would almost feel...well, invincible...
