It's funny how some weird stuff happens in my dreams that trigger my lucidity but a lot of weird stuff don't. I may be in a desert with pigs flying around while a snail is talking to me or whatever and i don't know that i'm dreaming. But, for example, if i try to talk and my mouth doesn't move or nothing comes out of it, i know that i'm dreaming. I guess i have to train my awareness a lot. Is that it?
Many of you might have a great sense of awareness to know right away that you're dreaming. I read Robert Waggoner's book and in most of his dreams, the different color of a door knob or a shorter hair of a friend is enough for him to have lucidity. Very simple stuff.
I still don't have that sensitivity, that ease to trigger my lucidity, but i do have some elements that trigger my lucidity right away. They are:
-unable to speak (paralyzed mouth or having no sound)
-being with people and then, all of a sudden, they disappear
-cannot find anyone
-a door too small or too narrow for me to pass through
-fire multiple shots at very close range to kill a DC and nothing happens to him

Those are my dream signs. Again, it's funny how weirder stuff doesn't make me lucid. Do you have this also? How can i improve this? And, by the way, what are your "lucidity triggers"?
