I've dreamt about butterflies three nights in a row, and only last night did I start to get suspicious. "Hold on a minute," I thought to myself, "You don't see butterflies flying around at this time of year! And that big white one with the strange spindly wings doesn't even look real!" Alas, instead of concluding that I was dreaming and proceeding to have a lucid dream, I instead concluded that it was probably just some species of butterfly I didn't know of.
