I was like that too. I remember having vivid dreams about my parents dying, one in particularly, involved them getting their heads cut off (but somehow leaving their skulls in tact), and blood everywhere. I was trying to wake up my mom (though her head was nothing more than a skull.) It scared me so much, that I can still remember it...

I'm not sure if it's normal or not to have those kind of dreams, but I know that I've always been edgy and paranoid, always having those types of dreams, and now I have emotional problems...
