I fell asleep close to 10pm and woke up as I was violently tousled in my bunk that sat just over the back wheel. I was startled awake and it took me a while to get a sense of where I was. I then remembered that I was on a bus to Phong Nha and that we should probably be there soon. In an intensely groggy state, I checked my phone to calculate the remaining time when I realized I had only been asleep for an hour and a half. It was just barely 11:30, and nearly everyone on the bus was awake.
