Adult Mystery/Horror where an invisible attacker falls from the ceiling onto a woman

[Lauren]

This may have been a short story or a novella. It was included in an Ellery Queen Magazine in the late 70s when I read it, but could have been from earlier for initial publication.

All I can remember is a woman lying in bed and an invisible man landing on her and attacking her.

This scene happens in a short story by Fitz James O'Brien: What Was It? - it is told from the pov of a male narrator, though. Maybe we can do some 'story similar to' search to find yours.
