Questions of the Paranormal?

No questions, but an interesting experience. Several years ago I was standing at the sink washing dishes. My cats went flying by and I turned to tell them to slow down and behave. To my surprise, there in the floor in front of the fridge were several drops of blood. Some were the size of a quarter, some smaller. I yelled for my husband to help me grab up the cats to make sure none of them were hurt. They weren't bleeding and neither were we. I recall looking at the ceiling and actually wondering if the house was bleeding. Several months later and uncle stopped by the house. He was reminiscing about times spent there as a boy. This is a family home. He mentioned that Grandma had held a straight razor to Grandpa's throat in the very spot that we had seen the blood in the floor. She didn't kill him, just drew blood. It hasn't happened since.
