I'm a very posative person but at random times I think about horrifying gruesome things. Usually about someone dying or getting seriously hurt. The other day my grandma was driving me home and she was hitting the corner a little to fast and I just thought " what if someone was around the corner and t-boned us and the car flippes over and we die in the car?" almost everyday I imagine me or a person dying and it makes me cringe because it bloody and gory. Is this normal?
