Your new doll...

You were in your room, Reading a book. Your doll was in the corner of your room sitting on a pillow, Everything was relaxing until the doll moved in the corner of your eye. You looked up and saw nothing moving so you shrugged it off. Then your mom came to your room.. Mom: Hey Y/N, Its time for dinner. You went down to dinner and a few minutes later...The doll moved spots. After finishing dinner you went back to your room and noticed...What do you do?
