They keep saying if you warg for too long you can get stuck and lose yourself - Bran is told that in a couple of different seasons. He carries Bran around like he is a horse. He takes orders like a horse. Bran can warg into him like he is an animal. He is scared of thunder and lightening like a horse. Just an interesting theory I read somewhere else!

This theory actually makes a lot of sense unlike my imaginative one :P
