For me there is but one piece of knowledge that is important -- "I think - Therefore - I am."

So I think dogs think also therefore "dogs are". Any one that has had a pet dog or cat know for a fact that they dream, so dogs and cats are. I am not sure about birds and bee's and cows or other animals.

Knowledge of oneself is pretty important, but I am not sure anyone really knows who they are from one minute to the next.
