Cabin Fever.

Brainteaser Answer 15:

The ‘cabin’ is actually a plane cabin and the two men died in a plane crash!

A bit grim, I must admit, but anyway…it’s all about the dual meaning of words again.

When you hear the words “forest,” “cabin,” “wood” etc. together, it (should) immediately conjure up images of a wooden cabin in the woods.

The picture association may also have helped to distract you from the real message… then again, perhaps you weren’t fooled at all?
