Guilt
Knowledge of a wrong you did — the specific weight of having caused harm you cannot now lift off the world.
Guilt in a dream is the dream's image of the specific weight of having caused harm you cannot now lift off the world. Guilt is not shame; guilt is about a particular act and is, in principle, answerable. The dream brings guilt when something in your life — a known wrong, a specific harm done, a failure you could have prevented — is requiring honest acknowledgement and the work that follows from it. Guilt named and worked on toward repair is the dream affirming the right use of the feeling. Guilt converted into permanent self-punishment with no movement toward the injured party is the dream noting that the feeling is being kept as a private penance, and the actual repair is not being attempted.
