Grey Cobra in dreams
A hooded snake that rears to be seen — a threat that displays before it strikes.
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 Cobra
A cobra in a dream is the dream's image of a danger that announces itself. Cobras stand up and spread the hood as a warning, giving the watcher a chance to back off; the bite is the second move, not the first. The dream brings the snake when something in your life — a person, a temptation, a decision — is currently in its display phase, and the warning is the gift before the harm. A cobra hooded and steady is the dream telling you to read the threat and choose. A cobra struck without warning is the dream noting that you ignored the display when it was offered.
