Eco-conscious sub-conscious?

The other night I had a dream where I dreamt about people throwing plastic spoons out of windows into a river (I don't remember the logistics, just the effect). I pleaded them to stop, as it was a big waste and bad for the river. They replied they liked watching how the spoons fell. I didn't think that I was feeling THAT bad about using a new plastic spoon for my daily yogurt. Apparently I feel very bad about it. I'll be bringing my own, re-cleanable, re-usable spoons from now on.
