I heard about a strategy for remembering dreams that did work for me, but to be fair, I already occasionally remembered dreams, I just wanted to remember them more frequently and with more detail.
The moment I wake up, I write down absolutely anything I can remember about my dream. I found that as I was writing, some details would come back to me. After a few weeks doing this, I was remembering many details from my dreams nearly every night, and even having what seems like more vivid dreams.
I did stop doing et EVERY day, cause for me, I just wanted to know if it actually works, but writing first thing in the morning every day felt like too much trouble. If I have an especially weird or vivid dream I do still like to write it down quickly just for the novelty of having a record of your own dreams.
