You're experiencing the effects of Douglas Adams' Total Perspective Vortex (from Hitchhiker's Guide to the Galaxy).
It was basically a torture chamber which inflicted the most horrific sort of torture imaginable upon its victims. How?
"For when you are put in the Vortex, you are given just one, momentary glimpse of the size of the entire unimaginable infinity of creation along with a tiny little marker saying, 'You are here'."
When the victim sees his complete and utter insignificance, his psyche is utterly destroyed beyond recovery.
