Damiana, cannabis and mugwort blend.
My ethnobotanist mixes and smokes in a 5 part ratio, 2 parts of either and one part of damiana.
Experiment with amounts though, for your own tastes
Strictly for dreaming, mugwort can be used at about 500mg-1g.
Mugwort makes dreams amazing in my experiences.
Edit: In my extremely relaxed current state I thought you meant for sleep-visions. Oh well
I believe in freedom for everyone.
