Sigmund Freud, "The Uncanny" (1919).
To some people the idea of being buried alive by mistake is the most uncanny

phantasy is only a transformation of another phantasy which had originally
nothing terrifying about it at all, but was qualified by a certain lasciviousness
-- the WELCOME HOME phantasy, I mean, of intra-uterine
There is a joke saying that 'Love is home-sickness'; and whenever a man
dreams of a place or a country and says to himself...: 'this place is familiar
to me, I've been here before', we may interpret the place as being his mothers'
genitals or her body. In this case too, then, the unheimlich is what was
once heimisch, familiar; the prefix 'un' is the token of repression.
