I've only had something similar happen twice, once with 3g's mushrooms and once with 6 blotters, and in that order. The mushroom experience was unlinke anything I had gone through previously, and remains the most profound of my life. I cant quite express the majority of what went down for me, nor recall much of it, but it was a mix of anxiety setting in (while I was in very high spirits, feeling the love, and plenty healthy), a wave of seizures, several trance states, time loops (determinism?...), a waking dream state (which apparently, never actually happened), and a physical pain beyond anything which the word pain might apply to.
The pain and the seizure permeated the peak, unfortunatley I have no way to say for sure how long that part was. As it came on, I remember being suddenly forced into an asana (yogic posture) and my hands were brought together, as my vision went molecular, down to atomic, to energy, etc and I collapsed backwards to the floor totally in blackness thinking "sensory overload". But I never actually passed out, I just went in and out of trances with the seizures. When the seizure would let go, I could open my eyes and see, then the physical pain would set in. I guess the only way I can describe the physical pain is that it felt like my central nervous system was being burst with electric fire, every nerve in my body was in an unbearable agony, and it was the only time I've been weakened to the point of wishing for death. I dont think I cried, not sure I even could have, but as the pain would taper off, the trance would take me to visions that were very dreamy, very different from the expected psychedelic mind imagery. This was somewhere that felt very real, in fact it still does.
The LSD experience I have only myself to blame; I bought a 10 strip and made the assumption that I had either been ripped off entirely or given a low dose, so I went ahead and ate 6 in the hopes that "maybe I'd feel a little weird." Five minutes after eating them, my perception of the world exploded into the geometric stage, I was given no time to play with the come up, Tom & Jerry conducted a seance in my living room, and I snapped out of it 6 hours later. There was a cascading pain throughout (everywhere, mental and physical) and upon regaining a nearly solid state of focus I was blessed with a very high state of euphoria though completley primal. Think of playing Final Fantasy VII at the Battle Square and having your level reduced with every handicap, it felt sort of like that lol.
The visions, sensual blending, emotions, communion with God or myself or whatever it is, and so on remain out of my league to expound upon or even describe at all. That state is rarely touched it seems, or at least I've yet to personally come across more than a handful who have been. It wasnt like dying, or ego dying, it wasnt spiritual or intellectual, or philosophical. It was an experience that continues to test my sanity, and while I haven't touched any psychedelic in almost a year now, my awareness continues to unfold, however I am not so proud as to omit the fact that I was not ready for either experiences and my personality flaws need to be controlled before I can go any deeper into it.
LSD I can handle and learn from, but mushrooms finally caught up with me. I feel like I've run into a wall made out of myself and shattered into so many fragments of being that the means with which I can progress are no longer to be determined by looking inside. Sometimes, we all need a helping hand.

lol) but to reject the mind and accept a soul or reject a soul and accept the mind are not healthy luxuries from which I may choose. The time loops had such an impression on me, that I feel the nausea of being as you mention often when the memory comes and projects two different paradoxical occurences. And the Middle Way in my opinion, only serves to block out that potential that there is no Middle Way, which I assume one must be a Buddha to put the money where they mouth is.
