Still, for me, once in a while I get to lucid dream, but not as often as I'd like. I tried focusing before sleeping on going into a lucid dream state, but it doesn't always work. Then, because it doesn't work for a couple days, i tend to forget to keep trying, and so i end up having no luck.
I love it when I do get into that state, I've been able to change scenery, people, situations, but it's so short lived. I maybe get a few seconds of it before i wake up.
