Dimple
A small natural indentation in the cheek that appears with a smile — a face's involuntary signal of pleasure.
A dimple in a dream is the dream's image of a face's involuntary signal of pleasure — the small natural indentation that appears only with a real smile. The dimple cannot be faked. The dream brings the dimple when something in your life — a moment of honest delight, a long-suppressed warmth, an unguarded response — is being made visible by a feature that the polite face cannot control. A dimple noticed and welcomed is the dream affirming the honest signal. A dimple appearing on a face that is trying to maintain a neutral expression is the dream noting that the interior feeling is leaking through despite the effort to hold a different surface.
