Schizophrenic delusions function as shields against death terror

Evidence

Schizophrenics like Pat are unable or unwilling to partake of a shared cultural belief system. Subject to bouts of overwhelming terror, schizophrenics construct imaginary worlds—which are as real to them as this book is to you—to counteract the dread. These phantasmagorical universes are often peopled with hostile and fearsome forces. — Sheldon Solomon, Jeff Greenberg, Tom Pyszczynski, The Worm at the Core, 689
