Hi, I am 20F and a week ago got back from a cabin trip, the next day I noticed a small lock of hair was cut on the top of my head under a small layer of normal length hair.

a few days later i see there is more hair cut from the the same spot. i have no idea what this could be, the hair is cut as if scissors were used and im just not understanding how or why this is happening. i have never had this problem before.

I am not sure what could have caused this, I sleep alone with no pets, i do have extensions but they are no where near the top of my head. my brother and dad who i live with have no idea how this could be happening either. i am also a very light sleeper.
