I See Dead People ... Really I think I did

So I'm walking in the park with Freckles and there is this woman sitting on a bench across the stream from where we are. She is older with a large straw hat. She looks at me and smiles and nods. Well Freckle did her business and I bent down to pick it up and when I stood up the lady was gone. Now she could have walked out of the park but I didn't see her on any of the walkways. She would have had to walk extremely fast to get out of eyesight that quickly.

So I wonder ... was she real or a ghost? Am I real or a ghost? Are you real or a ghost? Now I am off to work where, quite often, I see dull people.
