The term ''Thoughtography'' (also called ''Themography'') is the claimed ability by some Psychics to be able to ''transfer'' or ''burn'' images seen in their Mind, onto clear (undeveloped) photo paper or regular untreated paper. The practice was popular in the late 19th Century and early 20th Century as a form of ''Spirit Photography''. As we have seen, many of these examples were genuine hoaxes perpetrated on grieving families of recently deceased persons (as a means of getting monies from them). Several examples however are seen as being genuine or rather, were never proven tampered with. Highly debated even today, Thoughtography is rarely seen, outside the Horror Film genre.
