Coffee may cause ears to play tricks on you

It seems lots of coffee could cause your ears to play tricks on you. A new Australian study claims the combination of caffeine and stress can affect the likelihood of a person experiencing psychosis-like symptoms and hear things.

Researchers had a group of volunteers consume high levels of caffeine and listen to a white noise machine. They were told a song would play, and if they heard it, they should press a button.

The song never actually played, but several subjects actually thought they heard it.

Researchers say as little as five cups of coffee a day is enough to trigger the effect.
