I have accumulated more than 9 hours of sleep on occasion during LD training, but it's fairly rare. Earlier, when I would force myself back to sleep on those nights where I had no recall out of stubbornness ("I'm NOT GETTING UP UNTIL I RECALL AT LEAST ONE DREAM!"), dreaming in those extended periods actually was less aware then in the time leading up to 8 hours, by a considerable margin. So I just stopped doing that because the dreaming was poor and I'd feel sluggish all day if I slept too much.

FYI, I was in bed about 12 hours last night. I don't know how much of that was sleep, but probably most of it was. I was awake in the morning for a while (an hour at most perhaps?) and got back to sleep with my "back to sleep kung fu", and actually had some decent dreams including a late FA which I caught [more or less handed to me, I was ejected from the bed, love when that happens] and turned into a short DILD marred by pure caveman mode. p.s. I took 2 mg of melatonin last night because I was so jazzed from a self-pep-talk before bed about lucidity . So I may have had some REM rebound going on this morning.

DEILD allows you to get right back into it , so why not, I think it's a great thing
It *IS* a great thing -- but I guess I'm questioning how often "natural" DEILD opportunities arise. Maybe I'm just too far from DEILD on my mind, not tuned in well enough to wakings, or my bedroom conditions are such that those opportunities just don't come up more than once in a blue moon. Maybe alarm DEILD is a great way to gain a lot of DEILD attempts under your belt and so improve and create more opportunities. But I'd still rather just stay in the dream longer .
