Hi! Try to lie completely still when you wake up. Keep your eyes closed and focus on nothing. The dreams should start appearing. I usually "probe" for my dreams. If I wake up with a hunch, a single image or some random word in my head, I try to explore the thing. This usually leads me to recalling the entire dream. Try this if you don't get nothing after lying still. Also have the intention of remembering your dreams. You want to tell yourself: "I will remember my dreams". Good luck!
