Never heard of it! I know kratom has given me some crazy dreams. Quitting weed was the best thing I could have done for dreaming.

Not so much that I can't have crazy or fun dreams, it's just that even if I repeat them aloud after waking up they fade very very quickly. To get good at lucid dreaming you basically need to have incredible memory, or the strength to keep a dream journal that you do every night.

You very much have to train yourself to remember dreams, as well as a way to know you're in a dream. (Counting your fingers when crossing any door, when meeting or talking to people, finding something you do often in dreams that you can relate and instill a habit in the waking world, and then also training yourself to notice and understand what having 7 or 4 fingers actually means in a dream). There are many ways to train yourself, and to find your own "trigger" mine specifically is just looking at my hands and counting my fingers.
