Welcome to DV!

Supplements can give you some really amazing dreams. The only two herbs I've tried are Calea and Mugwort. Calea was kinda cool, gave me very vivid and stable dreams. I'm not sure I had the right dose or even the right plant, it was barely bitter and from what I've read it's supposed to be so bitter that you almost vomit.

Beyond Dreaming is a place on this site you should check out. These parts aswell: Lucid Aids

Keep on dreaming!
