Stuff that triggers lucidity and some that don't

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"?

Definitely happens to all of us. It's not only awareness, but also memory(not speaking about prospective memory). It's not that you are not aware to some stuff and some are, but memory plays a big factor too. pigs can't fly, and you know that, but when in a dream, your memory is "off", so you don't remember that these things are impossible.So, practice the fundamentals (self-awareness and memory). Sageous discussed these in his course http://www.dreamviews.com/wild/12557...mentals-q.html. Sageous teaches WILD, but these fundamentals are for DILD too.
My dreamsigns are my school and my father and friends, I have much more, but these are the most frequent. My friends are the most frequent dreamsign.
Good luck;)
