Welcome to the forum!

Well you need to be patient with the lucid dreaming, it takes time to do. Stay positive! As the other people have said, a DILD is a spontanious lucid dream and is what naturals tend to have. To be honest with DILDs you shouldn't really experience SP. If you are considering a WILD then I'd strongly suggest against it as it can be difficult and put people off if they don't LD from it. I always recommend doing a WBTB with a MILD.
