I hope this doesn't sound preachy or whatever, but I've never had any of those insane type of hallucinations on any dose of acid, and I've read (from 60s psychoanalytical literature) that "gross" hallucinations tend to be the result of suppression of the actual psychological content of the trip. Just a thought, of course I don't know this for sure.
That's interesting, relates to the experiences I was going to recount here...
One time I was meditating (LSD) at night in the Botanic Gardens, lying on my back, I saw the clouds were faces with all expressions of joy. They looked at me as they smiled, talked, laughed, gradually merging until there was one smiling face that nearly filled my vision, same size as if someone was inches above me, but the perspective seemed like they were a long way up. An archaic Sunday school teaching bleated that I couldn't possibly gaze upon the face of God, but there it was. Interesting thing about that night was that I had been hallucinating wildly until then (giant spiky blue dogs jumping out of the grass towards me, was convinced my bare feet were underwater, eyes in the trees, hearing trees gossiping in the wind etc etc), after I saw that face visual effects almost completely stopped. Just a few colours changing and extra acuity.
I had a vision with Very Similar meaning another time, I thought the acid I'd taken was pretty mild until I was given a spot of weed oil (maybe you know of the method as blades or hot-kniving?) about five hours after dropping. My flatmates went to bed but I stayed sitting on the kitchen floor, mesmerised by the river of moonlight flowing across the floor.
An earlier trip (two good tabs) was near totally filled with intricate hallucination, air visible as swirling blue streams, muscles moving under people's skin, hearing laughter blossomed huge flowers in my vision and so on. When the interesting train of thought began (my lineage, every cell leading me back down the path to genesis) I was just walking down the street thinking, not tripping, not hallucinating. Big thoughts though, and the sober moment only lasted a few seconds (the big thought was a subjective eternity) before I thought my two friends had been arrested and I might be next. Good thing I could distinguish between good and bad paranoia!
So it's hard for me to tell what the "trippiest hallucination" I've seen is, as the ones that really meant something were fairly uncomplicated, while the uber eye candy is fairly unemotive beyond the "WOW it's so beautiful it's setting a flame of joy under me".
