I invisioned these poor souls at any moment breaking down all their concepts of reality, climbing the walls like Jeff Goldblum in the Fly, only to lash out at family members then curl up into a fetal ball in the corner of the room. This would inevitably be followed by the vision of them crying hysterically about everything.

I never thought it would actually be something along the lines of driving down the road listening to Pearl Jam and ten seconds later mentally battling the urge to drive into oncoming traffic. Followed accordingly with hysterical crying. It's still scary though.
