Now my light has gone completely. I feel panic rising inside me. I shout, but of course hear nothing.

Then I just sit here in silence.
Eventually my ears must become more sensitive. Because I think I hear something, faintly, from a great distance. As if the sound is many miles away, distorted by the rock. It's my friends! Calling for me! I shout back but they don't seem to hear!
Should I stay still and experiment with different ways to be heard? Or keep moving in case I find a place where the sound is louder? Or do something else?
