'The Conjuring 2' turned out to be more of a horror flick than expected. It actually gave a heart attack Thursday to a 65-year-old Indian who died in Tamil Nadu, India.

He was a native of Andhra Pradesh, who watched "The Conjuring 2" in a Tiruvannamalai movie theatre with a friend. Suddenly, he found it difficult to hold his breath.

Before he could watch the film's climax to arrive at some solution to the suspense, he complained of chest pain and even fainted. He was rushed to an Old Government Hospital but could not be saved.

However, his friend was told by paramedics to transport him to the Tiruvannamalai Medical College Hospital so that he could undergo a postmortem. However, the corpse disappeared along with the friend.

Later media reports explain that the friend was spotted taking the corpse in an auto rickshaw, to their ashram, a spiritual heritage, where they reside. But the police were not able to find either the corpse or its friend.

Watching horror films such as "The Conjuring 2", has led to heart and breathing rates to shoot up phenomenally. A sudden suspense of the unfamiliar, or instant shock when an antagonist appears can lead the body to undergo terror, which directly attacks the heart.

Still, human psychology seems to revel in such effects. A 2013 study found that brain chemistry is vital in the human reaction to fear or distress.

Such a fear can shoot the flow of the blood from the heart to the extreme parts of the body, usually dubbed to be a "sensible evolutionary reaction to fear." With contracting muscles and rising cortisol levels, the eyes may move continuously, adrenalin levels can go up and some parts of the brain genetics respond.

Yet, even if humans tend to get fearful, they also seem to revel in such reactions. That is why the movie has grossed over $104 million globally.
