Elisa had always had the ability to see things that weren't there, whether it was weird figures, shadows, or glimpses of things in the corner of her eye... it was kinda normal to her now... though it still startled her sometimes

one day she was walking around her house, when she saw something move in the corner of her eye, she looked over, expecting it to not to be there... but it was still there...

Elisa: "...huh"
