My friend was a philosophy major and studied metaphysics, which really interests me. He said I can pick his brain, so I was wondering if there are specifics I could ask to help me understand metaphysics a little better?

I met a person who claimed to be a metaphysicist. Once over a telephone conversation, he told me to write a number down on a sheet of paper, then he guessed the number twice. Does metaphysics involve telepathy?
