I need help on how to have a dream as soon as I fall asleep or even later on in the night because, a lot of the time its just blank while I sleep and the next morning I dont remember a thing of the dream I might have had.

Like last night for example, I was trying to lucid dream and the whole night nothing happened. Then when I woke up I started remembering this WHOLE vivid lucid dream in my head.. but what I want is to actually go from sleep straight into the dream..

any help?
