What is the oldest memory you can remember?

Me earliest memory isn't a very great one. The fact it was horrible is probably the only reason I can remember it. Because I cant remember anything else from when I was barely a year old.

I was about a year old and my sister wasn't going to be born for another few months. My family was still located in texas where I was born. A tornado warning was going off and all I remember is it being very dark and being carried into a bathroom. I can also remember bits of my mothers voice, my crying, and alot of loud noise as the tornado went by and totalled half our house. According to my father it barely missed us but destroyed a good chunk of the place.

The memory use to haunt me alot when I was younger. Lots of nightmares of that thing replaying over and over again.

EDIT: I always thought old, important memories were just tucked away in the part of the brain we are not aware of? But you can remember with certain techniques to bring them out. That is what I've heard, anyways.

Jam it back in, in the dark.
