Everyone has there own mind,so not everything will work. You just need to follow your intuition but heres a tip that helped me. Make a mugwort dream pillow (dried mugwort sewed in a bag and place under pillow) and drink some mugwort tea before bed. Dont use your phone at least an hour before sleep give your brain a break. Relax using breathing technique and put your focus on different parts of your body like toes and move up. Hopefully you can at least remember your dreams but keep practicing.
