I had the most horrible nightmare last night.  It has disturbed me all day.
I don't know why my mind would come up with something like this.
Warning -  this is awful and disturbing:

In the dream, somehow my sweet little tortie, Toffee, was sliced in half.  I
was in a kitchen/operating room with my uncle who's a vet, trying to put her
back together.  My job was to keep the lower half of her alive.  He had to
take out some vertebrae to put her spine back together.  I woke up before
knowing whether or not Toffee was going to live.  When I got out of bed, I
ran around the house looking for her, and was worried because I couldn't
find her at first.  Of course, she was fine.
Why would I even think something like this?  It was so awful!
