Dream of big crab eating up smaller crab

Just like the idiom goes, big fish eat small fish, – the dream interpretation of the dream of big crab eating up smaller crab, goes along a similar line. The bigger creature bullies the smaller creature. The same species views the other of its own kind as a threat. It desires to protect its territory. It consumes the smaller creature to eliminate the threat. Creatures of the same species fight one another or devour each other.
