What do normal people think about?

I’m often told that I think about strange things, that I look at things in ways that they hadn’t thought of. So with the assumption that I’m unusual or abnormal for thinking the way that I do, what do normal people think of? When people see some random pattern, i.e. an ink blot, what do they see?

And is the fact that I’m wondering what normal people think about in and of itself proof that I’m strange?
