Back to basics

I can remember one of my first nightmares,
I was about 4 years old. I know this because I partly dreamed about my first school and I still lived in the house I was born in. I had a friend back then called Dory and we were playing in my bedroom.
Suddenly, the lights dropped and it was dark. All I could hear were the sounds of cats howling, kinda what you hear when they are in heat. I started calling for Dory and I heared her say something like: "Get out, hurry!" I started to feel the little paws and claws of cats crawling on me and ran to the bedroom door. I called for Dory again but there was no sound. I found the lightswitch of my desk and turned it on. All was dark but the area were I saw Dory laying on my desk, dead. And the cats started crawling on her. I ran away as fast as I could.

I believe this nightmare has haunted me for a few years. I never had such dead related nightmares untill I was about 10.
