A demon is often defined as a malevolent supernatural being or evil spirit, typically associated with the devil or hell in various religious and mythological traditions. In many belief systems, demons are considered agents of chaos and malevolence, tempting individuals towards sinful actions or causing harm. Unlike human spirits, which are thought to be the residual consciousness of the deceased, demons are generally regarded as non-human entities that have never possessed a physical form of their own.

Interpretation of a demonic presence manifesting in a physical space.

Across cultures and traditions, demons are often depicted as malevolent beings with the intent to harm humans or disrupt the natural order. In Christianity, demons are associated with fallen angels who rebelled against God, while in other belief systems, they may represent elemental forces or dark spirits seeking to influence and corrupt individuals. The concept transcends religious boundaries, appearing in various forms in folklore, literature, and popular culture as symbolic representations of the darker aspects of the supernatural.

In paranormal research, suspected demonic activity is often categorized by its stages: infestation, oppression, and possession. These hauntings are frequently characterized by an oppressive atmosphere, disembodied guttural growls, and unexplained physical attacks like scratches or bite marks. Because of the potential danger, these cases often involve collaboration between religious leaders and medical professionals to rule out psychological or neurological conditions before spiritual intervention is considered.
