Depends on the era. It depends on the shroom. It depends on the influence. If violence is the theme, what's your trip, what's that rush?

Those edible shrooms, dried out kind, cheap, taste like bark, just tend to make everything liquid. Like walls and shit start breathing, and rippling, or they become liquefied? Like ripples, such as waves and buoyancy, kind of like veins running through them. It's alive, you start feeling a wall or some shit, like your beer can, thinking it's really moving. Why is that vagina biting me. What? Then there are the reflections and the shadows. But most of the time, unless you're eating them by the kilo they don't cause much other shit. But there are the more potent ones, life threatening, toxic, they can send you right out for hours into places that can be bad or good depending on your high.

Wasn't LSD created by those lab geeks for manchurian candidates. Post hypnotic suggestion? It is far stronger right. Those trips hallucinate much more, and depending on its dosage can be quite fatal.

But we're talking a ritual to encourage frenzy and blood lust. It was likely the shrooms, because other plants weren't as available to them.
