Regi,
Dream journaling is the first step. Right down your dreams right away in the morning, Even if you don’t remember anything, write “cannot remember dream.”
A trick that helps is waking up in the early morning (a few hours before you would normally wake up). Go back to sleep but try not to drift into unconscious sleep, repeat the pphrase “this is a dream” as images start to appear.
Try doing reality checks during the day. I like looking at my hands, concentrating on the details and saying “this is a dream” several times a day until its a habit and then you do that in your dream.
Good Luck and hopes this helps!
