After I had my first lucid dream a while ago, I had my second 20 days later, and my third about 20 days after the second. After the third, however, I've been having a lot of dreams that are sort of lucid, but barely. For instance, the other night I had a dream where I walked into my room and found that a girl I had gone out with earlier that night (in real life) had left me a love note on my desk. Somehow, I SORT of knew that I was dreaming - since I knew I was dreaming, I decided that I'd write down the letter in the dream on another piece of paper so I could look at it later (not realizing that the paper I was copying it to was also part of the dream.) When I read the note, I noticed that when I concentrated on the sentences, a lot of words repeated ("how" was written three times in a row sometimes, etc), but I accepted it because I knew it was just a dream and my mind couldn't display it right. Either way, I managed to write it down, and although the paper I wrote it on obviously wasn't there when I woke up, I still remembered what the letter said.

My question is, is it normal to have a lot of these low-level lucidity dreams after a while, and is it good? I haven't had a dream that was as lucid as my first or second in a while - is it necessarily a good trend that I'm having a lot of far lower level lucidity dreams lately?
