Dream or Nightmare, becoming real?

I didn't do anything special today, it's just to hot. But what I dream is very odd.
I first dreamed that Siel and Christina both died, and I was becomming depresife.
Next night I dreamed that my twin sister was ill
And the night afther that night I dreamed my sister was going to die.

What is creepier than dreaming that your twins sister gets ill and dies... and the next day you find out that she's ill and becoming more ill. O.O

I'm not going to sleep anymore!
