Its for real. I work in a facility for the mentally ill, and we have a set # of pts who are up, wandering, stealing, fighting, smoking, etc ALL THE TIME. Full moon comes, they're asleep in bed. The other ones are up running around then, and then there's the shifts in behaviors, delusions, hallucinations, etc. For a bunch of people who can't be in tune with when they gotta pee, they sure are in tune with full moons.
