I don't EVER get lucid with RCs anymore. I've only had a couple dreams in which I got lucid because of them.

My theory is that, if you honestly think or ask to yourself that you're dreaming, then it most likely is, so you just beleive it. Some people need that extra reassurance of RCs, some don't, I don't. sometimes when you're on the fence RCs do help, but you will sometimes just know. Sometimes I think that I become lucid just because it has a "dream feel" to it, kinda hard to explain. I don't mean seeing the unordinary, just that it doesn't seem real. In a recent almost LD I didn't become lucid because I didn't think that it had a "dream feel" to it, as part of the reason. I suppose since it was very vivid.
