When I was younger, I would get this same nightmare over and over and over but somethings changed in it. The only absolute was that I was killed. So ya, here goes nothing..... I would "wake up" in bed and I would hear a growling sound. When I looked with my peripherals, I would see a huge black dog the size of a tiny horse. The dog would be looking at me gnarling his teeth and with blazing red eyes (note that I am actually scared by red eyes or demonic things which may have been cause by this dream). He would then proceed to maul me and I would try to fight back but he was too big (someone goings to take this out of contexts ;)). Almost every night, I would get this dream. I continued to try and fight it but couldn't. But then years later when I was a teen, I started getting into mythology and reading books about it. It just really fascinated me. Well, I came across the Percy Jackson books. I enjoyed the series a lot and when he came out with a little short book. There was a picture in there that had an all black dog with red eyes. It practically looked like the one from my dream. Needless to say, I could sleep well for days. It really freaked me out. When I eventually got some sleep, I woke up to hearing growling. Now, I had my dog in my room so I thought it was her but I looked and the asshole was there about to pounce on me. This time because I was much older and not as scared. I killed it but I died to. It had a look of surprise in its eyes when I did. I was happy that I finally beat it but sad a little to. I care about animals a lot so even though it "hurt" me, I hated doing that. So I went to sleep the next night and it was there again. This time though, he wasn't gnarling his teeth or anything. He proceeded to go next to me and nudge my face lovingly. I thought to myself what the -blam!-. He then stood facing away from me like he was guarding me now.
