Ever so often I dream about eating meat. They are really annoyingly realistic dreams. As an example, here is the one I had last night.
The scene: some sort of country-style buffet restaurant. There's bacon. Everybody sitting with me has bacon. I remember really liking bacon. So I decide I will by god have some damn bacon! And I very slowly eat about half a piece; the first bite's pretty good, and then it's less good, and at about the halfway part I begin to feel ill. Also everyone is looking at me like I'm crazy.
Which is about what would happen if I did, in fact, eat the damn bacon. If I'm going to dream about the stuff, I'd rather enjoy it. Sheesh.
(Also, recounting this dream has brought up some sort of sense-memory, and now my mouth tastes like bacon. I am going to go get a glass of water, because it's icky.)
