Hypnographic Imagery?

I saw a post about this and had never heard or tried it..i have yet to have my first lucid lol..but one of the ppl in that post was responding about how they sorta of picture the stuff playing in thier head and it becomes more realistic sumhow till it IS the dream..like as ur falling asleep...im i natrually reaching for a known technique? can sum1 explain ?

what is explained there is VILD (Visually Induced Lucid Dreaming), although it is possible to lose consciousness before lucidity with VILD. Or it could be WILD (Wake Induced Lucid Dreaming). Either one matches what you've said.

5-6 hours of sleep is recommened before trying these techniques.
