I took a break from lucid dreaming because I was having so many false awakenings and short dreams that it was disturbing the quality of my sleep. I think training in lucid dreaming caused my mind to spend more time in REM at the very cusp of waking. For about 3 hours each morning, it would just be a blur of phenomena like dreaming of being awake, dreaming of dreaming, recalling previous dreams within dreams, mistaking daydreams for sleeping dreams. Like a stone skipping on water.

I think I reached the point where my mind was primed to become lucid but the novelty had worn off and I wasn't really motivated and didn't have any specific goals. Eventually, I took a break, turned my intention to NOT become lucid, and my sleep returned to normal.

I suppose each dreamer needs to find their own balance. I think it's not so good to be in that half-committed mode where you want to become lucid, but you don't have any goals and aren't enjoying it. Either be fully on or fully off. Or maybe develop a more structured schedule like only attempting on weekends to maintain a balance.
