Parapsychology is the study of phenomena that cannot be explained by science such as telepathy, intuition, telekinesis, and near-death experiences. It explores topics like transferring thoughts without senses, gaining information remotely, and the mind influencing physical objects. Parapsychologists also study precognition, clairvoyance, psychokinesis, apparitions, and concepts related to life after death like reincarnation. They research these phenomena through methodology, experiments, and publishing results.
