# undoMemoryDream

Memory: undo one dreaming change (`eventId` from getMemoryDreamLog): what it retired or merged comes back, what it wrote is forgotten. On a waiting trust proposal it DECLINES the step. Accepting a trust step is not an operation: the person does it in the app. Refused when a later change depends on it.
