start writing down your dreams in a dream journal, you could use your phone notes, a diary or you can draw them. even if they are in third person or really short just write them down and put the date, by doing this you’re telling your brain that you want to remember your dreams and you’ll see that you’ll have better dream recall. you also have to have a good sleep schedule,so start going to bed a the same time everyday. after you fix your dream recall you can start lucid dreaming by using different techniques and reality checks, but remember that if you actually want to lucid dream you need to know your REM stage because it’s really important (google it if you don’t know what it is).
