Parapsychology is the multidisciplinary study using the experimental method of phenomena that involve the psyche and its interaction with the environment.
These phenomena are called Psi phenomena.
The founder of this discipline is Joseph Banks Rhine.
Parapsychology was a historical successor to metapsychology, which studied sleepwalking and mediums in the 19th century.

Parapsychology studies psychic phenomena not explained by established scientific laws, such as telepathy, precognition, psychokinesis, and near-death experiences.
