Telepathy is the ability to communicate with another person without using any physical means of communication. It is also known as PSI, which stands for 'PSYCHIC' or 'PARANORMAL' phenomena, and ESP, which stands for 'extra-sensory perception'. Telepathy is a form of extrasensory perception that allows people to transfer thoughts, feelings, and images from one mind to another. It is believed to be a form of communication that transcends the physical world and is often used in PARANORMAL investigations.
