in my long past experience with these substances I consider one in particular to stand out as potentially having been a rglimpse at levels of reality not normally available to us.
This came about after a friend gave me a bag with some dry Liberty Caps ;Psilocybe semilanceata
https://en.wikipedia.org/wiki/Psilocybe_semilanceata This specie has a high concentration of the actives psilocybin and psilocin .
I;d guess from what I can recollect this having now been over 30 years ago the bag held about 3-5 grams.
After ingesting my friend went off on his own and I found myself alone in a field off River street in Santa Cruz,CA mid afternoon.
the first extraordinary awareness I have tried to describe as if the top of my head had suddenly disappeared and I was no longer enclosed within my mind as an individual consciousness..
During these brief moments self awareness was mostly absent in that perception of surroundings created no impression of being in any way distinct or that in perceiving no sense of separation between external and internal or me and that existed . Like there simply was no Me or I and that no idea of 'myself' as being distinct from what I observed was either absent or could or ever had existed.
I have considered what we have from the Book of Genesis describing the original state of Man knowing neither Good nor Evil and having an immediate immanent relationship with the Creator.
This came about because of the other feature of this fleeting experience.
The profound sense that I had company.. that I had in a manner of speaking entered a dimension of Eternal Being and there was an Eternal Living Presence which gave me a sense it was aware of me.
Soon after that though a self aware thought arose in my mind which to that point had seemed I later described as a "room with no furniture" that I might appear strange to passersby who could see me standing in that field with a stunned look of amazed incomprehension on
