One time, I was camping in the wilderness and heard rustling outside my tent in the middle of the night. I peeked out and saw a pair of glowing eyes staring back at me. It turned out to be a cougar, and it was so close I could see its teeth glinting in the moonlight. I had never felt so simultaneously fascinated and terrified in my life. I managed to scare it away with some loud noises, but I didn't sleep a wink for the rest of the night.
