I think most cannabis have low levels of hallucinogens but enough to access some of your soul or spirit. At first i thought it was just my mind playing tricks on me but i think it is much more. Now in the spirit world there is no sense of time so when you are on hallucinogens and hear voices i think sometimes it is a residual sound left from people that where previously in the surrounding area. I think the soul is primitive and the spirit is ancient.
