Something in my phone

Okay people might think im crazy and stuff but this is true and scary. One day I took a picture of myself in the dark but had the flash button on on my phone. when I looked at the picture it was a picture of this skeleton face or something. the picture was like a weird color like a orangeish color I guess I dunno. I showed my mom and she said that it could be something watching over you like a family member or something. I started showing people in school and a boy noticed something else in the background of that picture. It was like not human at all. it loked like it had a sword or something. I kept looking at the picture everyday to try to figure out what it was. the picture started fading away slowly until the face was gone. A few days later the picture dleted itself or something. I know im not crazy because other people have seen it. I dont know does anyone have any clue what it could have been?
