Black Stamp in dreams
A small piece of authorisation affixed to a document — the official mark that the thing may now travel.
How black changes the reading
Black colour pulls the symbol toward the not-yet-known — depth, hiddenness, the part of the situation that has not yet come into the light. The dream is rarely warning you; it is showing you that there is more to the picture than the part you have been looking at.
The base reading of Stamp
A stamp in a dream is the dream's image of the small permission that lets a piece of work leave your hands. Stamps are not the writing; they are the authorisation that the writing is ready to be sent. The dream brings the stamp when something you have prepared — a letter, an application, a decision — is finally being released into the world. A stamp affixed and the envelope leaving the house is the dream marking the release. A stamp held but never applied is the dream noting that the work is ready and the permission has been written, but you have not yet let it go.
