Jar of pickles
A glass jar of preserved cucumbers in brine — stored sour, sealed under a lid until needed.
A jar of pickles in a dream is the dream's image of stored sour sealed under a lid until the day it is needed. The pickle jar is patient; it waits in the cellar and does not require attention. The dream brings the jar when something in your life — a kept grievance, a preserved memory, a sharp truth held for the right occasion — is sitting in storage and remaining ready. A jar opened at the proper meal is the dream affirming the use of what was saved. A jar found long after the brine has gone cloudy and the lid has bulged is the dream noting that the kept sour has fermented past what was intended, and what comes out of the jar will no longer match what went in.
