is it true or purely coincidence?

hey my lovelies.
It's been cold lately, because it's rainy season now.
brrrr....

oh, lately I always get nightmare and it's almost 3 nights already.
I don really remember the details, but it's pretty scary.

two nights ago, I dreamt that I was possessed by an evil spirit.
It was pretty scary, you know! really scary!!!

last night, I dreamt that someone intend to kill me with bombs!
Gosh!!

I read somewhere about this cold weather. It says 'The colder the room, the higher chance for you to encounter with nightmares'.....

it's pretty cold these two or three days. Even my roommate decided to turn off the fan because it's bloody cold, like Iceland!

Maybe it's true then.......
Nightmare......
