Eastern State Penitentiary is described as a paranormal hotspot due to its history of brutal solitary confinement, which is thought to have left behind lingering dark energies and hauntings. Visitors and paranormal researchers report experiencing unexplained phenomena, including seeing shadowy figures and ghostly apparitions in cellblocks and guard towers, hearing disembodied voices and laughter, and feeling unexplained cold spots, sudden pressure, and physical sensations like being gripped. The prison's crumbling structure and isolated atmosphere contribute to the terrifying and unsettling experiences reported by those who visit the site, which hosts both museum tours and a popular annual Halloween event. Shadowy figures darting along walls, ghostly faces in cellblocks, and dark figures at the top of guard towers. Disembodied voices, echoing laughter, tormented screams, and even the sound of a dog howling or pacing. Overwhelming pressure, chest pain, shortness of breath, an oppressive atmosphere, and the feeling of being physically gripped. An apparition known as "The Soap Lady," a mysterious woman seen by employees, and tormented faces appearing on the cell walls. The prison was once known for brutal punishments, including extreme isolation and forms of torture like the "water bath," which left prisoners in extreme cold.
