Secret
A piece of true information kept hidden — a fact whose withholding shapes the room it sits in.
A secret in a dream is the dream's image of a piece of true information whose withholding is now shaping the room. Secrets are not neutral storage; they redirect the conversation around themselves. The dream brings the secret when something in your life — a fact about the past, a feeling, a plan — is currently being kept from a person whose relationship to you depends on knowing it. A secret kept for a clear, defensible reason is the dream telling you the discretion is honest. A secret kept past the point where its keeping is the actual cost is the dream noting that the withholding is now the harm, and the original concern has been outgrown by it.
