And now you can't get in touch with the girl to see if she is alright? It is hard to see something like that and it feels traumatic. Especially if we are vulnerable to anxiety. If she is a friend, can you give the family a call to see how she is doing? Otherwise, if you are dreaming about it, it is just a way for your subconsious to work out your emotions surrounding it.
Would your parents be open to you seeing a therapist? Just wondering. it could be nice for you to have someone to talk to. good luck
Literaly happened............. :'(
Are you saying this happened while you were at school or you dreamed it??
