Waking up with water in the tent is always fun......
One of my first forays into tent camping, we set up in a "nice little cleared spot" it rained hard all night and it turned out our nice spot was in a depression. We had prob 1" water in the tent and simply sat there waiting for the lightening to quit. It was a long night. I was about 15 at the time and learned a good lesson in site prep.
I also spent a night in temps in the teens with a '20 deg' sleeping bag. EN rating took on new meaning for me after that. I wasn't anywhere near hypothermia but sat there with all my clothes on waiting for daylight, kind of sucked.
Also spent a night with a camp visitor that wasn't afraid of being yelled at, headlamps, or apparently anything else. Judging by the tracks, I'd say a 200 lb black bear. Our campsite wasn't his first visit. There is something about having a large creature walking around your tent in the dark, only separated by nylon.
