Weirdest dream...?

i have this reoccuring dream i have had it like 5 or so times... where i am walking down the park in Ecuador...i lived there for like 5 years, im walking down this park field type thing.. and then the sky turns dark and i start seeing birds flee and i start to get really cold till i can see my breath....then i see these cloaked things with black dogs in chains start running at me....and i try to stand my ground and be strong...and i guess it kinda reminds me of like the fight against good and evil? i am wearing white in this dream and more and more black images start walking towards me...some are flying like demon looking things.....and some on the ground...and i look back...and i see a whole army of white images...behind me.... some are flying as well.....and then the armys clash against eachother.... in my dream i dont feel scared but i get knocked out, and i wake up and nobody is around me.....i have wounds and stuff from the war and thats when i wake up from my dream...
