Hello. I have had only 1 truly lucid dream in my life, and it lasted about a second, but I have had a few FLDs. I temporarily stopped trying to LD after I realized I wasn’t getting enough sleep, but now that I feel better about my sleep schedule I’m ready to begin learning to Lucid dream!
What most people agree on is that the dream journal is the most valuable tool. But whether you use one or not the key is to draw out the dreams into conscious thought so you can clearly remember them in full while conscious, and have conscious experience of the dream world. But of course having a record you can search through is very useful, to notice the patterns like what happens often and what never happens, and what effect trying different things has on your dreams, especially if you don’t have a perfect memory of every single dream you ever had!
And remember that everybody is different, so the advice of others may or may not be helpful to you. And unless you are lucky it’s probably going to take some time.
I’m lucky to remember my dreams a lot, unfortunately I forget to do RCs and that is my main issue
