It just happened that I chanced upon dream herbs a while back. Mugwort to give as an example. I became acquainted with having a cup of it as an infusion some evenings. As a sporadic drinker I can say you're assured to dream not your average dream. But dream you will. Today I came across Calea Zacatechichi in a book, though having previously known about it, I decided to order it in dried form. I am hoping to experiment.
