Grey Albatross in dreams
A long-distance ocean bird — a burden you carry, and the long journey it implies.
How grey changes the reading
Grey colour layers ambiguity onto the symbol. The base meaning is still there, but the dream is saying you do not yet have the colour information — the situation has not declared itself.
The base reading of Albatross
An albatross in a dream is two old images at once. It is the long-haul traveller who can stay aloft for weeks without landing, and — through Coleridge — the weight a person earns by harming what should not have been harmed. The dream brings the bird when something you did, or failed to do, is now travelling with you for a long way. An albatross flying freely is the dream telling you the burden can be released. An albatross hung around the neck is the dream naming a guilt you have not yet found a way to set down.
