One question that sometimes comes up during paranormal investigation is how to tell if paranormal activity is the result of a ghost or a demon. There’s no easy answer because the two are so similar. Every case is different. Ghost activity can be mistaken for something demonic and demons are known for imitating human spirits (often the ghosts of young children.) While it can be almost impossible to determine the difference, here are a few points to help narrow down a culprit.
Ghost activity occurs both when people are present and when no one is home.
Ghosts often appear in locations where a tragedy occurred. They also tend to return to locations or items that were important during their life.
Ghosts have the ability to create cold spots in the atmosphere.
Ghost activity is generally harmless. While ghosts might frighten someone, it’s often accidental or playful in nature.
Ghosts usually stay in one location. The rarely leave their territory.
Demonic activity tends to wait to occur until someone is around to witness it.
Demonic activity usually occurs in locations where séances or satanic rituals were (or are) practiced. Look for reversed pentagrams, Ouija boards, candles placed in formation etc…
Demons have the ability to manipulate the temperature in a room. They can make it extremely hot or cold. People suffering from demonic possession sometimes run high fevers.
Demons often try to harm people they encounter. People can be scratched, shoved and may experience vivid nightmares or hallucinations.
Demons sometimes follow people to other locations and may torment them for years.
You should never try and determine whether you have demonic activity without the help of a professional. There are no rules that apply 100% of the time when it comes to ghosts and demons. I also did a post on the signs of demonic possession a few weeks ago if you are looking for more detailed information.
