What age were you when you became conscious of yourself

The day that my mother, and I had to pick up my dead dog, Toby. He had been hit by a tractor, and I felt sorry for my mother, who had to scrape him off the street. I don't remember feeling sad, or anything for Toby, but I remember seeing his eyeball lying on the street, and steam was rising off of it, in the early morning. This fascinated me, and was my first memory. I was 1 yr. old.
