a dream about mike and metaphors

In a bid to make this blog a little more personal (though I hope anyone out there reading it enjoys the links/art/music) I want to tell you about a dream I had last night. 

I know, I know, I know. What is it that Dennis from It's Always Sunny said about dreams..."They're like pictures. If I'm not in them I'm not really interested"? I know, most dreams ARE boring, especially in their entirety. So I'll just leave you a snapshot:

My friend Mike explaining the nature of metaphors to me. He says that most people focus just on the binding aspect, how they draw two previously thought to be unlike things together. But there's also a fundamental separation that takes place also. There's a remnant of difference that's lost in the bid to symbolically represent similarity. Like the distinct details that get erased from caricature. Where do the remainders go?

He seemed to know but wanted me to guess. I woke up instead.
