A TRICK MY GRANDMA TAUGHT ME:
When you wake up have a journal and pen next to you to write down EVERY single detail from your dream you had the night before. As time progresses, you will have a dream every night, and start to remember everything, and finally gain the ability to control them.
I started in October of last year, I could remember everything by January and control them in February
and it is super fun to look back on all the crazy things you dreams about.
