A recent study conducted by a team of researchers from the University of Durham, High intake of coffee, tea and caffeinated energy drinks could be linked to a greater tendency to hallucinate.

The extensive study was conducted on 200 coeds, who were asked a series of questions about their coffee-drinking habits and what effects they noticed.

Study say, Among those who had a significantly high intake of caffeine had triple chances of having heard inexistent voices than their fellow students who relied on low coffee intakes, usually around one cup of coffee or instant coffee a day.

Other strange incidents except hearing voices, is sensing the presence dead people lives. Their proneness to hallucinatory experiences, and their stress levels, were also assessed.

According to the study, if caffeine is involved in triggering imaginary voices, it could be because it causes the body's levels of the stress hormone cortisol to rise, which may influence the development of hallucinations.
