Hi there, What does "things which go bump in the night" refer to? How is "bump" used in this phrase? I don't have much context. It was spoken by narrator Mary Alice in Desperate Housewives, at the end of an episode. She was talking about "moment of dread" "when we ask ourselves" various questions. One of them was, "Are there things which go bump in the night?" I'm thinking this refers to Juanita's fear of a killer on the prowl, putting her in danger. (The girl saw a horror movie and then was certain she saw the killer in real life. Then later in the episode, her mother Gabby saw someone through the window too.) Thanks!
