If they were representations of mental barriers, would that make me the curious part of your mind that wants to go look at it?

Anyhoo, I'm still fairly certain I'm not a mental construct, in part because I have thoughts of my own. Cogito ergo sum and all that. And I'm fairly sure the things I think aren't things you'd think. Let's just say things get very Freudian in here. Have you ever noticed how many things are shaped like a phallus?
