Ghost Hunting Groups and Ghost Hunters in Germany: Results of Two Online Surveys

Journal of the Society for Psychical Research March 12, 2026 Gerhard Mayer, Sonja Nowara

German ghost hunters are motivated by curiosity and prior exceptional experiences (ExEs), not distress. Two online surveys—21 teams and 39 individuals—revealed that ghost hunting groups (GHGs) share similar site selection, investigative methods, and use of technical equipment, but differ in documentation and data handling. Individual ghost hunters reported more ExEs than student samples and hold stronger paranormal beliefs. 85% believe in a link between paranormal phenomena and the deceased, yet 30% identify as atheists or agnostics, indicating belief in spirits is not tied to belief in God. For most, ExEs inspire further pursuit; nearly two-thirds said prior ExEs were key motivators for taking up ghost hunting. Motivation ranges from scientific interest to confirming or questioning personal beliefs.

Magic and Its Evaluation – Reports and Views of Practitioners

Journal of Parapsychology October 1, 2023 Gerhard Mayer

Magicians report experiencing phenomena such as influencing situations or weather, psychokinesis, ESP, and synchronistic events. Evaluating magical practice is difficult because success depends on the magician's goals, and displacement or trickster effects occur, similar to those in parapsychology. Preconditions for successful magic include motivation, an empathic relationship with the goal, no doubts about effectiveness, and not wanting or suffering too much. Dedicated magicians could aid parapsychologists due to their trained focus and ability to work with altered states of consciousness, though motivation may be a challenge.

A German online survey of people who have experienced sleep paralysis.

Journal of Sleep Research June 1, 2022 Gerhard Mayer, Max Fuhrmann

An online survey of 380 people who had experienced sleep paralysis at least once found that more frequent episodes were associated with more phenomena, emotions, and perceived shapes during the event. Some individuals appeared to habituate and de-dramatize the experience with higher frequency. Contrary to expectations, neither general stress nor poor sleep hygiene correlated with episode frequency. Women reported more phenomena and emotions overall, more intruder and incubus-type episodes, and were more likely to perceive concrete forms like human figures. They also reported more fear, especially fear of going crazy. These exploratory findings require replication.

Sleep Paralysis and Extraordinary Experiences

Journal of Anomalous Experience and Cognition May 13, 2022 Gerhard Mayer, Max Fuhrmann

Sleep paralysis is linked to some extraordinary experiences and paranormal beliefs, but not all. An online survey of 380 people who had experienced at least one sleep paralysis episode found a significant correlation between how often sleep paralysis occurred and scores on the Dissociation and External dimensions of a questionnaire about extraordinary experiences. However, no such link was found with other scales measuring paranormal beliefs or absorption. Among the 55% of participants who reported paranormal experiences during sleep paralysis, scores on all three scales were significantly higher. The results suggest two possible types of sleep paralysis experience: one tied to negative emotions and external focus, another to positive emotions and internal perceptions, but this hypothesis needs further testing.
