Mongoose
A small carnivore famous for killing snakes — quick, focused courage against a venom that should overwhelm it.
A mongoose in a dream is the dream's image of small, focused courage taken up against a danger that should, by size alone, win. The mongoose is not immune to snake venom; it survives by speed and by not flinching. The dream brings the mongoose when something in your life — a confrontation with a fear, a defended household, a stand against a long-tolerated harm — is being met by a part of you that is smaller than the threat and faster than it. A mongoose finishing the fight is the dream affirming that the courage was correctly sized. A mongoose bitten and not recovering is the dream noting that the courage was honest and the speed alone was not enough this time.
