Coffee 'triples risk of hallucinations'?

I ran into this article on the Telegraph.co.uk, and found it interesting on several levels.

It states that people who drink three or more cups of coffee a day, deemed “high caffeine users,” are much more likely to hallucinate, as in hear voices or even see things that are “not there.”

Like what?  The article specifically cites “hearing voices or sensing the presence of the dead.”

The researchers conclude that caffeine could heighten the effect that stress has on the body, triggering these hallucinations.  But then they admit it may also be a case of people who are more prone to hallucinations could also be more stressed and therefore more likely to consume large amounts of caffeine.

In other words, they don’t know if it’s the caffeine that’s causing it, or if the caffeine consumption is just another symptom of what ails them.

What I find interesting is that the researchers simply assume that the voices aren’t really there.  How do they know that?

Maybe, just maybe, caffeine heightens some people’s psychic abilities.
