As for different types of trips caused by the crystal, I believe that it stores intention, energy, and love during its life. Being exposed to positive energy and intentions aka love, gives it more of a personality imho. That could just all be made up bs but that is what I feel from it. As when I was a noob and still dealing with shady people with the wrong intention who sometimes get ahold of it etc those were the only times I had bad trips.
i see where you're coming from, but i don't really agree that a psychoactive substance can have 'personality'.
may i offer another way to look at the issue of getting bad trips from acid acquired though shady sources?
maybe they didn't didn't know what they were doing, so they didn't store it properly and it degraded.
that old chestnut "set and setting" can also account for a negative reaction.
this kind of hippie babble is very entertaining, but it is kinda bordering on superstitious peasantry.
