WARNING: DO NOT USE OUIJA BOARDS. THEY ARE VERY DANGEROUS AND CAN INVITE SOME VERY DANGEROS BEINGS INTO YOUR BODY!!!
OK, I was just reading a book about this and people can't seem to tell the difference between ghosts, demons and poltergeists. Thank God I'm sensitive so I cans et the record straight:
Ghost: A ghost is the soul and energy of a person who has moved on to the afterlife. Ghosts can appear in many forms: i.e. a misty cloud, a vivid light, a vapoury figure or even a full feature person. Many ghosts mean no harm and are just trying to send a message to loved ones before going into the light. Other spirits hang around due to unfinished business or torment: i.e. rape/murder victims, prisoners, soldiers, police officers, just to name a few. These spirits tend to be restless and will scream, howl or cry in pain, others are very vengeful and will physically attack people in vicious or dangerous ways. Angry spirits usually take on a black form, either a dog, a human figure or even a dark coloured vehicle, like a car or a truck. Some will seek revenge until their debt is paid while the tortured ones need to find closure. None the less, all tormented spirits need to be laid to rest before they can pass on to the afterlife.
Demon: A demon is a vicious, cruel being that is in no way human. While there is no conclusive proof as to where demons come from, there is some speculation that they are ghost that are so angry that they have changed into something dangerous, never to be tamed again. These beings take delight in torturing or harming a victim and once they latch on, they never let go. Some demons go as far as to physically kill their victims. Demons are extremely unpredictable and the only way they can get inside you is through use of a Ouija board, which can cause you serious psychological harm.
Angel: While an angel can be seen as the right hand being to God, angels actually have two forms. A demon is the second form of angel known as a "fallen angel". Angels can be seen as beings that watch over certain people and can be seen as rescuers for people in unfortunate events: i.e. a car swerving on its own to avoid a near fatal accident or a distraction that forces you to pay attention. They are seen as holy beings and guardians for people who are unfortunate in life, sort of an "overseer".
Poltergeist: A poltergeist is not in any way, shape or form, a spirit or ghost. It is actually resulted from a living person. Poltergeists is just the name given to someone who causes strange things to happen in their presence. They usually originate from teenagers and this is a poltergeist explanation. When a teenager is under pressure, their brain sends out electro-static waves. These waves can't be felt by humans and usually cause light bangings or thumpings. Wherever this teenager goes, the waves follow them. The more extreme the pressure, the more stronger the waves are and the violent they become. They can reach the point of knocking things over, throwing things around or bashing and banging on walls or floors. This only happens when said person is around. That is the explanation for a poltergeist. That is why a poltergeist cannot take on a physical form, as it is not a real ghost but the troubled sub-conscious sending out messages that move anything they hit.
There, all explained now!
