  After I  hurt my chin and went to hospital for a small surgery, I have been suffering from the same nightmare and it is quite annoying to me. 

  In fact,  I am not very scared but it's just make me annoyed and affect my sleeping quality.
I could not remember the content of the nightmare but I always woke up from the nightmare. 

  Is that something like Traumatic sequelae? Some fearsome feeling after a serous accident? 
Did anyone have similar thing before?
