Vomit in a dream is a metaphor that can represent the dreamer’s feelings about what has come out of the mouth of one who “spews bile” in waking life. Vomit can also represent anxiety, a common physical response to extreme forms of it in waking life. Finally, vomit can represent a symbolic “purge” of “acidic,” “smelly,” and “distasteful” emotions. Whose vomit is it?
