Blue Gnu in dreams
A wildebeest of the great migrations — the individual absorbed into a moving mass.
How blue changes the reading
Blue colour cools the symbol — calm, distance, the steady side of the spectrum. Whatever the base meaning, blue says the situation is operating at a temperature you can think in.
The base reading of Gnu
A gnu in a dream is the dream's image of life inside the great migration. Wildebeest cross rivers and plains in herds so large that the individual is functionally invisible; the dream brings the animal when you have, for a season, set aside your own pace to move with a crowd. A gnu in a calm herd is the dream telling you the collective momentum is currently serving you. A gnu drowning in a river crossing is the dream marking that the same momentum will, if you are not careful, take you over an edge the herd does not notice.
