Cavemen

In this dream I found myself wandering a barren landscape of rocky hills and plantless desert.  After stumbling around aimlessly for a while, I happen to find a small family of cavemen.  There was a man, a teenage boy, and a young girl, none of which could speak my language.  The entire time I was with them we were hiding from something that I wasn't aware of.  After struggling to teach the cave people a few words in my language, we all went into their cave to sleep.  There I taught them how to bar the cave door to protect them against wild animals in the middle of the night.  Their cave was lit with 100 candles, how they learned to make wax is beyond me, and I had to go around blowing them all out before we all curled up on the floor of the cave to go to sleep.
