Some thoughts on Ghosts

I have read a lot of scary stories, watched a lot of horror movies, and read a lot of so-called real paranormal experiences. From my vast vicarious experience of the paranormal, I know that many things indicate the presence of paranormal entities.

For example, in haunted places, strange voices can be heard. Things get misplaced, small children can see things(even talk to things), animals react abnormally, etc. Some cases involve people smelling strange smells, from the odour of flowers and perfumes to foul or putrid smells. Some very unnerving experiences include hearing odd sounds like footsteps, bangs, scratching, moans, screams, music, whispering. Some people claim to have seen floating lights and shadows and things seen from the corner of the eye. Some experiences involve doors, taps, and light switches found open(or close), objects lost and sometimes recovered, objects falling from their places(paintings, ornaments, etc.).

Most of the experiences mentioned above have logical explanations. Many are interpretations where one impression received by our senses can be misinterpreted as another. For example, most of the strange sounds and screams might be caused by the wind. Object movements can be attributed to memory lapses. 'Seeing' lights and shadows may happen when our brain is exhausted. But some of these things can't be explained.

A haunted house

I have observed one common thing among all these experiences and I'm sure you must have noticed it too. There are certain areas in these haunted places where people have experienced a sudden feeling of coldness. It's like you walk just 5 metres away and you feel a sudden drop in temperature. And this may happen even during summer. It is the most common experience that occurs together with other things such as objects moving, children/pets seeing things, footsteps, etc. These places are known as Cold Spots. I thought about it a lot. What is the purpose of Cold Spots? 

Moving objects and causing sounds/voices takes energy. Now, unlike us, ghosts/spirits can't consume food to create energy. And if you don't have the energy, how'd you manifest yourself and how'd you scare people by moving objects and making sounds? My theory is that these Cold Spots are the places from where these entities absorb thermal energy and transform it into kinetic energy (for moving objects) and sound waves. It is kind of like a solar cell, more like a heat cell. Though my theory directly contradicts the second law of thermodynamics, I think this is the reason for the presence of Cold Spots, if ghosts exist.
