Extrasensory perception (ESP) refers to the ability to receive information without using the known human senses. It is often associated with phenomena such as telepathy (mind-to-mind communication), clairvoyance (gaining information about distant events), and precognition (predicting future events). ESP is a topic of interest in both psychology and parapsychology, though it remains controversial and lacks scientific validation. Many people believe they have experienced ESP, citing instances of knowing who is calling before answering the phone or sensing danger before it occurs. Despite numerous studies, the existence of ESP has not been conclusively proven, and it is often met with skepticism in the scientific community.
