If accuracy is the worry then placing this the exact quote from pikhal will clear anything up for the future ofthis thread
"PLUS FOUR (++++) A rare and precious transcendental state, which has been called a 'peak experience', a 'religious experience,' 'divine transformation,' a 'state of Samādhi' and many other names in other cultures. It is not connected to the +1, +2, and +3 of the measuring of a drug's intensity. It is a state of bliss, a participation mystique, a connectedness with both the interior and exterior universes, which has come about after the ingestion of a psychedelic drug, but which is not necessarily repeatable with a subsequent ingestion of that same drug. If a drug (or technique or process) were ever to be discovered which would consistently produce a plus four experience in all human beings, it is conceivable that it would signal the ultimate evolution, and perhaps the end, of the human experiment." – Alexander Shulgin, PiHKAL, 1991
to me this seems like a "transformative" experience where you simply surpass yourself or go past previous conventions so even religious experiences while tripping are considered +4, they seem to just be personal and very humbling, taking one beyond something or to a place in trips that is signature to them, as a result I can understand and accept a large amount of +4 experiences occurring and being reported, god looks different to everyone.
when I was on methamp and LSD the feeling was of great bravery in the acid state of mind and I wasn't so much inside my body I discovered(to my own interpretation) the center of consiousness being outside of the physical body it was in the area surrounding it and I was that consiousness, but I was also all my friends especially for interacting with the flawless humour that we entertained eachother with the whole night, very out of body and not as apparent on hallucination as much as a shattering of perspective, i felt no physical effects anymore but I was some extreme emptiness that was inheirent in all and everything, what was me was merely the area that was being perceived and I was increased to span several beings... "group mind".
very different from the +2 or +3 i've had because those are usually anxious until i come fully up and very ego bound still with varying degrees of personal security and confidence during, my +4 was of buddhist serenity and grand instinctual animal wisdom entering my body as i opened it and became receptive rather than bound. I felt alien and I fell in love with life and being again in a new way.
