One of the more unique dazed and confused stories I've heard:
A friend of mine used to work with a mining company. They had a project in a remote location in Laos, fairly close to the Thai border.
While their living conditions were comfortable, the only available comforts that didn't involve driving several dozen kilometers through dense vegetation were what could be had in the camp. After-work activities settled into a routine of gathering together with his mates and applying generous volumes of alcohol to numb their sense of boredom.
One evening, one of the guys whipped out a batch of cookies. These were goodies he baked himself, and liberally laced with weed he likewise hand-picked.
My friend decided to play safe and only consumed half a cookie. Within the half hour, he thought it prudent to lock himself in his room. He spent the rest of the evening trying to convince himself that all those shifting colors and sliding movements weren't all that bad.
He managed to stagger out into the fresh air the next morning. He spied the camp medic, one of his companions the previous evening, hooking himself up to a bag of IV fluid. It was an effective way to quickly rid yourself of a hangover.
As it turned out, the two of them got off comparatively lightly. A bit later in the day, they watched as another of their companions shuffled back into camp, half-dressed but fully-packed. He thought, the previous night, that the bad men were attacking and out to get all of them. His immediate thought was of escape. He awoke in the sunshine, alone and out in the jungle, with a backpack worth of canned beans and tools.
