I woke up with this scratched into my arm.If you cant tell it says \"HI\" I honestly didnt do it to myself but through the night when it happened I had horrible dreams and woke up trying to catch my breath.Ive tried everyway possible to debunk it but I cant Im positive I didnt do it to myself as I sleep with my hand under the pillow it wasnt my bed or my dog because I sleep with the door closed.It really shook me up...but the weirdest part was the day before my friend wrote hi on my hand and I woke up with hi scratched on mine.Its just really freaky!
