Large parts of the German population report extraordinary experiences: 75% had at least one extraordinary experience in their life, 50% report classic paranormal experiences such as hauntings, telepathy, extrasensory perceptions, or prophetic dreaming. Thinking you are crazy is a popular reaction from laypeople, but not infrequently also from professionals. Dieter Vaitl gives an overview of the decades of empirical research of the internationally known Instituts für Grenzgebiete der Psychologie und Psychohygiene in Freiburg im Breisgau. Most people can accordingly process extraordinary experiences well and incorporate them into their everyday lives, but some of those affected experience confusion and fear. Using modern psychological explanations, Vaitl explains when such experiences develop into a mental disorder and which factors play a role. He gives an empirically informed insight into the phenomenology and scope of a fascinating area of ​​our everyday reality.
