You wake up in absolute darkness. On your back. As you attempt to assess your situation, and gain your bearings, you realize that you are enclosed in what appears to be a wooden coffin. You have a zippo lighter in your pocket that you just filled up yesterday, and a pocket knife with a three inch blade and a can opener in the other pocket. You have no idea how you got here. The last thing you remember was drinking at a tiki bar with your friends while vacationing in Jamaica.

Write your way out of this in the first person. no divine intervention or other miracles. make it plausible or don't bother.
