so i've been reading these tutorials, and am i to keep a journal for as long as i can and noting what happened in the dreams and my feelings. then for reality checks, are they meant as if i think something is odd in the day or something weird i look back and concentrate on it to make sure its fine. then eventually will i automatically lucid dream, or how does this process work of actually lucid dreaming?

i'm wondering as well is lucid dreaming an exciting experience compared to regular dreaming? will you always remember how to do it when you're older, or once you stop practicing it you will go back to dreaming regularly?
