I assume that by FLD you mean false lucid dream, or something of the sort?
It seems you were pretty close, by this i mean that LD'ing was obviously on your mind for you to have these dreams. What i would suggest is firstly, dont get discouraged. All of us here are fully aware of how frustrating it can be to feel like your close and then have it slip away.

Unfortunetley, it doesn't work in the way that once you get up to a caertain level you stay there. Things can happen that knock you off your so-called "Path to lucidity" Nothing is wrong at all, everybody experiences spikes and falls in dream recall, just keep your head up, keep plugging away and you'll be lucid in no time
