The term extrasensory perception is misleading, as it probably involves the entirety of our sensory systems, possibly except for the sensors themselves (because for example, some eyeless people practice eyeless sight). The inputs are collected from everywhere and often from everywhen and then seem to be processed mostly by the normal routes of our nervous systems.

The psychic seeing, feeling, and hearing are also called clairvoyance, clairsentience, and clairaudience respectively, but the last two terms are almost in disuse. The word clairvoyance is often used as a synonym of the all-encompassing extrasensory perception.

There are psychic techniques such as psychometry and remote viewing (RV) that allow one to get all sorts of sensory information, and others that focus on perceiving particular type of information, such as scrying, which allows one to obtain visual information, and dowsing, which allows one to “feel” or sense the location of objects without actually seeing them. A particular type of seeing technique is the Ganzfeld protocol, which allows one to telepathically see what another person is visualizing in his/her mind. The psychic perceptions can become so real that one gets the sense of an absolutely real experience as is the case of the out-of-body experiences (OBE) and the very similar near-death experiences (NDA) or the precognitive and clairvoyant dreams. In the case of eyeless sight, one perceives the surroundings with fidelity enough for performing everyday actions such as reading, driving, etc.
