This was an interesting story I've been telling my friends and co workers. I felt it was good to share here as well!
A few weeks ago I had this strange nightmare. I own this cameo that I haven't worn in some time, it's been sitting in my jewelry box. In the dream I decided to ware it but, instead of the woman's face in profile, she was full-faced head on. Her featured are distorted, twisted, and demonic. The face was horrifying but I put it on anyway. I went through my day at school but everything was dark, twisted, and hazy. I also heard dark demonic voices and people's faces where brutalized. When I got home I was alone and frightened, something was also at my window trying to claw it's way it. I tried to take off the necklace but I started to hear a horrible screaming and the cameo started biting me. I woke up shortly after that.
I told my brother the next day about the dream. He thought it was pretty creepy, but I was able to creep him out more. The necklace in my dream I bought almost a year ago. It was at an antique shop in Orange. The necklace was tucked away in the shop and locked in a case. I had to get the store clerk to unlock and get it for me. I have no back story for it, it's origin is completely unknown.
Here is the actual cameo. Demonic entity? or a simple cameo? You decide!
