Very Scary Nightmare!!!

Last night I had a very scary nightmare... Gosh!! Why I always dream of something scary and creepy? This is really bothering me or maybe it was just my psychology that last night weather was hot and I can't sleep properly and I have this nightmare!

My nightmare story goes like this:-

All of the sudden, I was in an ambulance and I was like in the middle of an emergency. And sitting opposite me was a female nurse and on my right site was a male nurse. And there was a male patient lying on the bed too. And the nightmare starts here. I saw the male patient was half burns and his skins are like sprayed by acid in which the skins were peel that exposed flesh and white bone were protruding and the male patient seems to be so much pain and he even shouted but I can't hear his scream. And then, I was awake....

And I actually have no idea what was happening to the dream but it still circling in my head until now..
