Dreaming about an elephant can mean you want more power. It can also mean you think of yourself as overweight. An elephant is of course a very large animal and a very heavy one. Dreaming about an elephant could mean you think of yourself this way, as sometimes we dream about things that we think WE are like.
It could also symbolise wisdom as they’re animals that move very slowly and also seem to be old as they’re wrinkly. This could mean they’re seen as wise because we associate old age and slow movement with wisdom and knowledge.
