What Are The Disadvantages Of Watching Horror Films?

Horror movies can generate fear, anxiety, sleeplessness, phobia and mental trauma. They can also cause behavioural changes. For example, if someone watches a horror movie, they may be influenced by the film and change their behaviour to that of the villain's.

I remember the first time I had seen a horror movie on HBO. I kept it thinking in my entire sleep that similar things were happening with me. Next day too it had just occupied the whole day on my mind. Then I vouched never to see horror movies at night.
