Wood Paneling

When I grow up, I want to drive a car with wood paneling on the side. Why in the world do I put fish into my drawings so much? It escapes me. I can figure out the rest of the stuff, like disembodied arms or legs mean a feeling of helplessness or whatever. But fish are such constants in my artwork, and I don't know why. I've started to get mad at myself when I draw fish, because I want to know what they mean. If any of you are doctors of any sort and know what these fish mean, tell me.
