Most times from my experiences a spirit will attach itself to a person due to they are a weak link, they are not all that strong to fight it off and they are not believing into the power of God and the belief of prayer.
Usually before you go into any haunting situation and/or even a graveyard and/or somewhere that is haunted with entities and/or spirits.. you will want to do a prayer of protection and when you leave a prayer of leaving everything that was there, to stay there and not come with you.
Spirits tend to attach only because they can. And will.
Unless you are protected and use the proper spiritual prayers and symbols, holy water, salt and blessed rosaries, bibles, and even spiritual stones, to keep you protected.
I know this as the fact that I do belong to a paranormal group here in Maine and this is what they do before and after entering any place that is haunted.
Also another reason for attachment as silly as this may sound. Remember a spirit is usually human. They get bored of the same area as we do and would like a change as well. So they want to travel with you.
Another reason is that they are evil and like to torment you as well.
So they attach themselves.
The way to rid of it is prayer and sage helps and if it is really strong. Sometimes a Clergy or Priest or can get involved. Remember attaching is different then possession that is a whole other category and question.
Maybe the ghost is shy? It may have a reason against the person.
Depends on the skin color of the ghost when they were alive. Like if the person was white the ghost would be whiter
Ghost hunting is a pseudo science and there is no "official" certification for it. Even if someone were offering such a certification, it would be meaningless.
Probably because it is hungry and hopes that you will feed it. Cats do associate humans with food, and a cat that has been abandoned to fend for itself may try to attach itself to a passing human if it is not able to feed itself as well as it would like.
The ghost would win first, and then Dracula would win second. Dracula would grow weak and tired chasing the ghost. The ghost has no blood, so Dracula would starve to death while he tried to catch the elusive ghost. Once Dracula dies, he would become a vengeful ghost, who would then wear the first ghost like a coat.
Ghost, the witch has better powers but it couldn't touch the ghost, so ghost would win.
Mostly, they appear and the person with the view of the ghost would be horrified and may faint/scream or plain, just think it is a normal human being
You have to remember that a ghost is simply the disembodied spirit of a person. Therefore a ghost can make any sound a person is capable of e.g howling, moaning, wailing, talking, screaming, crying, sighing, etc. In stories, especially childrens stories, the traditional sound/word would be "Boooo".
"Malevolent" means "evil-doing". A malevolent spirit would be a wicked bad ghost. Applied to a living person, this would mean that the person is evil and rotten and mean.
That depends on how you know it was a ghost, and how you know it was Satan's ghost. People who claim to have seen a ghost do not - generally - know whose ghost it was. Those who believe in ghosts tend to think that they are the spirits of dead people. Those who believe that Satan exists would say that Satan is neither dead nor a person, and so cannot have a ghost.
An adaptation would be the setea (or little hairs on each segment). They are used to help the earthworm move in the soil and attach itself if it feels threatened or in danger.
No, it isn't possible scientifically to attach REAL wings to a person. It may be possible to attach mechanical wings, but it is doubtful. The strain and extra weight could possibly snap ribs, your spinal cord, or pinch important nerves in the spinal column. The strain alone on muscles would be painful. It would also be extremely expensive. So, it is perhaps possible, but it is highly doubtful that any medical surgeon would do it, or that anyone could afford it.
