Thanks, I didn't know. I do know that foods and vitamins for dreaming is a better way to go. For example the B3/B6 and tryptophan (found in chicken/beans/lentils) help promote niacin and improve dreaming.

Also anything that boosts cognition like Omega3 fats and exercise (20 minutes of jogging promotes blood flow to the brain and improves cognition) also benefits dreaming because the brain repurposes itself for dreaming. Healthy brain, healthy dreams.
