So, some people believe that there are ghosts in this world. The souls of dead people are moving around us without us noticing them.

But if that were true, the earth must be pretty crowded with ghosts, just like those japanse rush-hour trains, since there have been so many dead humans in the history of mankind. If all the souls are floating around on the earth, we must be passing through them almost anywhere we go. Also, when I take a shower, I’m thinking I’m alone but if this hypothesis were true, the bathroom if full of stranger souls…not a very comforting thought.
