How and why do people experience poltergeists?

People often experience poltergeists through unexplained phenomena such as objects moving, strange noises, or disturbances that seem to be linked to emotional stress within a household, particularly involving adolescents. Theories suggest that these experiences may be manifestations of repressed emotions or psychological energy, rather than supernatural entities. Cultural beliefs and personal interpretations can also influence how individuals perceive and react to these occurrences. Ultimately, the phenomenon continues to intrigue both skeptics and believers, as it blurs the lines between psychology and the paranormal.
