Paranormal events are purported or imagined phenomena described in popular culture, folklore, and other non-scientific bodies of knowledge, whose existence within these contexts is described as being beyond the scope of normal scientific understanding. Notable paranormal beliefs include those that pertain to extrasensory perceptions (for example, telepathy), and the pseudosciences of ghost hunting, cryptozoology, and ufology.

Retrocausality, or backwards causation, is a concept of cause and effect in which an effect precedes its cause in time and so a later event affects an earlier one. In quantum physics, the distinction between cause and effect is not made at the most fundamental level and so time-symmetric systems can be viewed as causal or retrocausal. Philosophical considerations of time travel often address the same issues as retrocausality, as do treatments of the subject in fiction, but the two phenomena are distinct.

Retrocognition (also known as postcognition or hindsight), from the Latin retro meaning "backward, behind" and cognition meaning "knowing," describes "knowledge of a past event which could not have been learned or inferred by normal means." The term was coined by Frederic W. H. Myers.

Table-turning (also known as table-tapping, table-tipping or table-tilting) is a type of séance in which participants sit around a table, place their hands on it, and wait for rotations. The table was purportedly made to serve as a means of communicating with the spirits; the alphabet would be slowly spoken aloud and the table would tilt at the appropriate letter, thus spelling out words and sentences. The process is similar to that of a Ouija board. Scientists and skeptics consider table-turning to be the result of the ideomotor effect, or of conscious trickery.

Thought-Forms: A Record of Clairvoyant Investigation is a theosophical book compiled by Theosophical Society members A. Besant and C. W. Leadbeater. It was originally published in 1905 in London. From the standpoint of Theosophy, it offers views regarding the visualization of thoughts, experiences, emotions and music. Drawings of the "thought-forms" were performed by John Varley Jr. (grandson of the painter John Varley), Prince, and McFarlane.

Thoughtography, also called projected thermography, psychic photography, nengraphy, and nensha , is the claimed ability to "burn" images from one's mind onto surfaces such as photographic film by parapsychic means. While the term "thoughtography" has been in the English lexicon since 1913, the more recent term "projected thermography" is a neologism popularized in the 2002 American film The Ring, a remake of the 1998 Japanese horror film Ring.
