Etymology
Origin of phantasm
First recorded in 1175–1225; from Latin phantasma, from Greek phántasma “image, vision” (akin to phantázein “to bring before the mind”); replacing Middle English fantesme, from Old French, from Latin as above
Explanation
If you've ever caught a glimpse of a ghostly figure late at night, you've seen a phantasm — something that only appears to exist. A phantasm is an apparition or ghost, something that seems very real when you see it but less so as time goes by. It's not real, but an illusion or brief hallucination that might be caused by a vivid dream, illness, or a lack of sleep. The Greek root is phantasma, "image or phantom," with in turn comes from phantazein, "to make visible."
