Dragon Dream

Dream: There is a huge ugly dragon after me. This takes place in a modern day city. First it battles with some helicopters and I can see the explosions in the distance. Then it returns for me. It came slicing through the sky like lightning.
I am holed up in an abandoned single-wide trailer. There is an old man there too. He's got a .22 which isn't enough gun for this occasion.
Still, he manages to bring it down and someone else chops off its head.
I was convinced that it would spring back to life but it didn't.
I woke up (4am) and it was hotter than hell in the house and I had a stomach ache. I turned on the A/C, went back to bed and slept better.
