Maybe you aren't at work right now. Maybe you aren't wearing a suit. Maybe that giant polka dot bunny can't hear your thoughts. Maybe you just drank too much coffee.
Researchers from Durham University (queried, we believe) 200 non-smoking participants, taking into account their intake of tea, coffee, energy drinks, caffeine pills or coffee consumed on an average day as well as their propensity to see things that were not there, hear voices, and/or sense the presence of the dead.
It was found that 315 milligrams of caffeine (about what you'll find in three standard cups off coffee) increased hallucinations by three times, though it's unclear as to whether or not this data could be correlational with crazy people simply drinking more caffeine to begin with.
