Encounter with observer

"We need to talk" said he, as I was cleansing my teeth with the sand. I removed the contents of my mouth. 
He indicated with his tone that something alarming had happened. Without knowing that stranger, I sat down the pool in the cave. He was standing far away from me. 
" You have intruded into my home. I was away to another place for the night and you took advantage of that. I had trust in humanity so I left the cave open for forlorn travelers. But you dig the grave of my shadow on the floor here."
" I am so sorry, Sir, to have caused you so much pain. I must not have let myself me taken stray by my temptations. I dug as I thought this place was not inhabited. I took your grounds for granted".
"Vanish before I bring my wrath upon you".
I ran as fast as I could. And that's where I lost more than a quarter of my treasure. The biggest mistake of my ever. 
My bag of sin is heavier now. Only a true soul can now save me through a regenerative energy transfer.
