Without being able to describe it myself, I am pretty sure I know more or less what you are talking about.
It is truly astonishing that Little Mushrooms can take a person to such places and feelings.
I myself was just a chap playing around with mushrooms for colors and a good time, but then one night the Little Mushrooms had other ideas for me and blasted me into a space where I discovered my true-self, experienced death and rebirth and perhaps even a glimpse of what the Universe is really about.
I have since loved the mushrooms with their much deeper meaning, their strength to change a person for the better, their way to give me back my feelings.
But what still fascinates me is the states and places these little ones showed me, where are these places and what are their meaning. This has not been revealed to me.
It is an interesting topic that I would like to hear more about from others.
