I am fairly new here, and have had about 6 LDs so far (in the last 6 months or so)
The main thing that led to LDs for me was journaling EVERY dream I had, even if it was just a snippet I could remember. I think this was a BIG bridge to bringing awareness to dreams and “building a bridge” from waking life to dream life. I also fall asleep saying “May I awaken in my dream and grasp the fact that I am dreaming…” to myself. I also think reading this forum helps to get LD-ing into the psyche.
When I don’t do these things I mentioned, the LDs go away.
EDIT: PS Stephen LaBerge’s book is VERY helpful too…
