So I hear that milk and dairy products make dreams more vivid and thus help with lucidity.
On satarday evening I had I glass of milk before bed, and that night I had and LD... last night I did that same, and although I didn't become lucid, the dream I had felt so real it was untrue, I've never had a vivid dream like that for months...
I've been toying with the idea of trying B6, but I think milk is working fine on me!
