The explanation is kind of obvious. On that day, I saw a woman with her fluffy white dog. And while we chatted she grab-petted her dogs fur. The dog shed. Later, I remembered that on the same day I spoke with a friend about confetti. He told me that once people threw confetti into his mouth.
I don’t know how my brain put these two instants together, but it did. Funny enough, I could trace the dream back. I was at school, standing at the board with my teacher who looked like Elvis. Next thing I know was that Elvis stuffed a big raccoon into my mouth. It was disgustingly hairy. Choking and panicking, I went circling around the classroom like a cartoon figure, trying to get the furry ball out of my mouth.
