So I did a quest were I had to give up all my gear except some clothes and my axe and bow. I finished the quest and went to sell the loot. So I went to whiterun and sold all the armor and other things I picked up, even the armor I was wearing. Walked outside to fast travel to get my gear back and a dragon appeared... And I'm naked besides my axe and bow. Thankfully I was in a town, were others could help.

What was your worst timing for a dragon to appear?

When a dragon lands and eats the NPC I'm about to get a quest reward from.

Then, it flames me afterwards.

On my way down from High Hrothgar, my character was level 4 and didn't have a follower. But it was fun!

Fast travel to Dawnstar to kill that guy for the Dark Brotherhood quest and notice a dragon circling, no big deal since he's just flying around. Kill the guy and the whole town comes after me so I figure i'll sprint out of town, fast travel somewhere and come back to pay my fine. Well the dragon decides now is a good time to attack me, so I summon my two lords and let them have some fun. Out of somewhere comes a bear swiping at me so I paralyze it and run around when I notice a new blood dragon has joined the fray. I now have two dragons, guards, townsfolk, and a pesky bear all coming for me so I pop Become Ethereal and watch the chaos for a bit. I finally reload my save and take care of the dragons and that bear before I make my kill on the DB quest.

After some tough fights with magic users my warrior was low on health potions and out of fire retardant foam. I was attacked by a blood dragon who proceeded to breath flame upon me. Ran out of health, ran out of food, my meager 100 points of magica didn't last long since I only had a restoration skill of 17. But I was winning. Just as I was about to put the killing blow on the blood dragon, another dragon landed right beside me and attacked. It was a short fight. RIP dovahkiin.
