Is there someone else here?

Is there someone else here?
maybe they're waiting for me
like I for them.
This is a vast chamber I'm stuck in,
and it's, oh, so dark 
I can only hear some chatter
it's low and loud.
Is it talking back to me?
Oh, oh maybe I'm really not alone
Is there someone else here?
I scream and my throats on fire
Wait, wait, I know now
'tis was only the echo of mine
although I can hear footsteps quite fine.
But I cannot trust my senses here.
So to not get eaten by my fear,
I truly hope, that
There is someone else here...
