It seems as though LDing two nights in a row is out of reach for me. I'm not "primed" for a lucid until I've had a few nights of failing to lucid (hence Failure to Lucid Dream Induced Lucid Dream). It's not as though I would be short on regular dreams if I did lucid every night, I have an average of 3 hard to remember ones in the first 5-6 hours, about 2 vivid ones in the next 3-4.

I think it might be a matter of motivation. After LDing, I'm pretty happy with myself, maybe I'll get lazy and not record some of the less interesting dreams, or not stay up as long after the 5-6 hours. When a few days pass without a lucid, I start to get frustrated and worried if I still have the ability, thus try harder. Obtaining resolve is still not enough, the first couple of days weren't considered failures since I didn't try; a couple more days of really failing, then I have a chance.

When I try and fail, my theory is it seeps deeper into the subconcious. Like how it's easy to dream about things that cause stress, the stress of not luciding can trigger lucids. Stress as in worrying about what you're doing wrong and if you'll lucid again.

FLDILD isn't exactly a technique I'd like to rely on.
