Cats are Sacred

I just read something odd. I was reading about dream interpretation and did a search about cats-because I see my cats in my dreams often. Apparently, seeing a cat in your dreams is ill fortune. That doesn't seem right to me, but of course, I love my cats and wouldn't want a dream where I killed one of my cats just to maintain good fortune. Yuck. How horrible. What is so negative about a cat? I think they are sacred. Perhaps the author of that perception is biased against cats. My cats most likely stand for other things, and not what some dream intepreters say. Also, they could just be in my dreams because they are a part of my life, and for no other reason than that.
