Adventurer, Be Thankful...
Thankfully, becuase of your superior packing in Step 2, you survive!
Due to the fact that you packed carefully, without blindly following a list in Step 2, you chose to bring a synthethic sleeping bag. When you got in it with your wet clothes, it became damp but due to its robust design (compared to a down sleeping bag), it still retained your body heat fairly well. As a result, you manage to make it through the night.
