A few months ago I had lung surgery. Anesthesia really fucked me up, and I would have nightmares, which made it hard to sleep, and then I would start seeing shit.
One night when I couldn't sleep, I was watching tv, and I saw the most horrifyingly real wolf walk in front of my TV. It was huge too. Size of a large bear. It looked at me, and snarled. I quickly pulled the sheets over my head, then I passed out.
