Ghost story continued

I have been reading a book on the hisorty of mining in Utah.  It is a great book; it talks about the early miners and who was in power and whe they found precious metals and how they found them.  It was funny because even the book said that it was mostly luck as to who found these minerals and wehre they found them.
Anyway, to go with my ghost story of my previous post.  I was reading a chapter on mining superstitions and it talked about "Tommy knockers" and what not.  The part that got me was it talked about miners in the early 1900s hearing noises as if people were working the mine.  They knew these mines better than anybody and they knew that nobody was working these areas or that the vein had ended and it was a dead end tunnel and nobody was down there.  Yet, they still heard these noises of people working the mines and they would sometimes hear these "miners" talking to each other as they worked. 
This was written in a mining history book that was published in 2006 with many of the information coming from PhDs and professors of history.  I'm only saying this to make people believe my story a little more.  And I'm saying this because the paragraph in the book sounds exactly like what I heard down in that mine that day.  It was very surprising to read something that was so close to my story. 
So if you still don't believe me then you need to come with me one day to one of these mines and we will try to get a ghost experience.  At the very least you will see how utterly quiet and dark the mines are and how it is extremely unusual to hear anything like we did.
