> Is there only one consciousness in the universe, or multiple?

This sounds similar to the "how do you know you're not dreaming?" question.

When you are in a dream, you really are the only single conciousness of that world. Any other person you interact with inside your dream is not performing any thinking of their own. Instead, dream interactions are just your single consciousness interacting with itself.

I think it is obvious there are multiple consciousness in the universe and not just one. Unless you're in a dream right now ;)
