The Uncanny (Ger. Das Unheimliche — literally, “un-home-ly”) is a Freudian concept of an instance where something can be familiar, yet foreign at the same time, resulting in a feeling of it being uncomfortably strange.
Because the uncanny is familiar, yet strange, it often creates cognitive dissonance within the experiencing subject due to the paradoxical nature of being attracted to, yet repulsed by an object at the same time. This cognitive dissonance often leads to an outright rejection of the object, as one would rather reject than rationalize.
The word sounded like “Heimlich” as in “maneuver”. Henry Jay Heimlich , M.D. (born Henry Judah Heimlich; February 3, 1920), is an American physician, has received credit as the inventor of abdominal thrusts, also known as the Heimlich maneuver. So, if his family name had been Anglicized, we would all be calling it the Homelike maneuver which does not sound as scientific.
