i actually don't do lucid dreaming much these days because of work, and my recall isn't that great. i know that i have no conscious awareness of such 'fogging' (i.e. my mind doesn't *feel* fogged), although melatonin might have an adverse affect on recall that i don't know about.

i haven't done any serious testing with melatonin and recall. however, i would imagine that you're more likely to remember something like a WILD because you actually transition into it from the waking state, which you will of course remember unless perhaps you do a DEILD.

the one thing melatonin is good at though is getting yourself to those final stages of relaxation before sleep paralysis/hypnogogia more quickly, which seems to be the problem posed by the post.
