This morning I dreamed I was drinking water and there was something in it. I poured it out, and it was a tiny brown spider. It ended up on my forearm. I tried to flick it off, and it bit me. I continued trying to get it off with very deliberate scratching, but it just stayed on my arm. I couldn't even feel the spider when I was trying to scratch it off. I thought there was something wrong with my vision.
