Scary Doll Dream

The dream started off with me sitting on my bed on my iPad when I felt something on my sholder. So I knew my iPad could reflect what was on my sholder, so I moved my iPad so I could see what it was. When I looked I froze in fear there was the doll from Saw (even though I haven't seen Saw the movie but I researched this after)and there was also one of my fake Halloween decorations, a skeleton with old cotton like a blanket wrapped around its neck. And it was hanging from the top of my ceiling. After that I woke up and ran to my parents room. . .
