The scientific name of ghost is ectoplasm (I hope I spelt it right). These Ectoplasms are energies left behind by people when they die. Since when a person die, his energy does not get destroyed and that there is no change from the energy to another except perhaps by the loss of heat energy to the surroundings. Among the energies unlost is kinetic, potential and life energy. All the above mentioned except life can be lost fast enough or completely disappear. This energy is ectoplasm or Ghost. The reason why a child or kid fears ghost more or more afraid of ghosts is simply because young children are more sensitive! A baby's hearing, sense of taste, smell and touch is much more powerful than an older person simply because they are delicate. They are sensitive to the surroundings and the slightest difference in temperature would affect a baby. For example, when we drink the water to be luke warm, the young child may find it scorching! Same for the detection of paranormal activates. A kid or child may find one place eerie but an adult won't!

Some people find that listening to a Hi-Fi or watching television will help rid of the eerie feeling felt. Well, that is true! As an energy, ghosts are easily affected by electro-magnetic waves or any other sort of energy waves e.g. Sound, light or even magnetic waves. It sorts of disrupts the ghost itself. That is one reason why we can't feel eerie when we are under the sun especially when it shines brightly. Heat in the form of radiation along with light energy is dominant and thus ghosts are then rather unable to appear. This theory somehow coincides with the ancient Chinese theory of Yin Yang. Where Yin represents Night, darkness, women...etc and here Yang represents the Sun, light, men....etc.

This is also one of the reasons why ghosts always and are mostly seen at Night. The Moon only reflects a very small portion of the Sun's powerful waves, therefore it appears that the Moon's glow is soothing and sometimes eerie this is because the reflected waves are longer and weak.

New ghosts (recently deceased's energy) have much more energy than old ghosts as no matter what, they will lose energy over time on Earth. The only way is to perhaps enter an Energy Realm that fits their kind of energy e.g. Heaven or Hell or else they may simply disappear forever and fail to exist.

Poltergeists are in this context real. As mentioned, ghosts are energy sources and would therefore be able to move objects, perhaps some really energetic ones can even emit sound waves (talking). Some energetic ghosts may even be able to emit light waves (glowing), that's why we have the white sheet as the ghost. Since these ghosts are energy forms, they should have the ability to possess someone, either on the reason that they need energy to sustain their existence or revenge or whatever. However, before they are able to possess someone, ghosts must first overcome the human's brain waves and perhaps the powerful fear waves which are the human's body's form of defense against possession. However, positive feelings waves are a much more possible defense but can anyone feel happy to see a hideous ghost? Neutral feelings are rather very useless but not the feeling of confidence or secure. Young children are mostly emitting powerful fear waves and thus, it is unlikely that a ghost can possess , even if the ghost did successfully possess, it is unlikely that the ghost would have enough energy to take control of the entire body or kicking out the original spirit residing in the body so it is only possible that the ectoplasma is only able to influence or control certain body parts or incite certain thoughts. However, ghosts that successfully take control of the host and riding the original residents are reported but only really powerfully ghosts are able to do such on really weak-willed creatures be it humans or some animals.

The Ultimate Friendly Ghost's wav file.

Cats scream and dogs bark when they detect some paranormal activity is simply because they hope that the sound waves would help, most of the time they do, but there are some exceptional cases. Ghosts pass through material e.g. doors.. etc is due to their energy-like existence like heat energy is able to pass through metal successfully...etc but ghost tend to lose energy quickly if they keep repeating this feat or the change-shape feat. Ghosts can gain their energy levels if the reside in a electro-magnetic wave environment as like living creatures that heal and grow, ghosts can produce energy and may grow powerful if their production of energy is faster than their energy lost to their surroundings. However, with modern technology and natural reasons, it is highly unlikely that there are any or much more wave-free environments left. Thus the reports on ghost are inevitably decreasing.

GHOST from a Christian point of view

Christians should not believe in ghosts. Because it is clearly stated in the Bible that the dead either go to Heaven or Hell to await Judgment Day (Revelations). No purgatory is mentioned though. Let's say the spirit if the dead is in Hell, do you think that Satan will say...okay, it's holiday time, you may leave hell and ease your suffering for a while. Go up to Earth and warn them about Hell."

There is no spirits allowed out of Heaven and Hell. There is no holiday in Heaven or Hell. Spirits are confined to their places. The so-called spirits are the devil's tricks to make us break the commandment of "NO NECROMANCY AND DIVINATION" stated in Exodus in one of the many other laws God set for the Hebrews other than that of the 10 commandments. The devil uses our love for the deceased to make us sin and to hurt God. This should never be allowed...of course...this is easier said than done to resist temptation.

So please do not believe in the dead coming back to talk to you. It is a trick by the Devil. God does not allow the spirits of the dead to come back to Earth from Heaven and Satan wants them to continuously suffer in Hell and there is no Holiday in Hell.
