The Ultimate Vampire Resource and Directory

Okay I work at a hospital that is stictly no smoking inside or outside! Well three times now while I was outside smoking I saw something that I just can't explain. I had the feeling when I saw it of something dark & depressing! More so it made me think of death! The first time it rather scared the shit out of me. Each time when I have seen it, someone dies! It's kinda disturbing to me! This is my first job in the medical field & I'm starting to remember why I never wanted to do medical! I had seen this once before or at least i'm pretty sure it was the same thing! I looked out of someones window once to seeing it going up the street! That was years ago & to my knowledge no one died that night! It's almost as if it's a taunting dark mist or something floating, kinda hoovering! Not something I want to be seeing & don't really understand! All I hav figured out is that when I see it someone dies & sometimes if I take a 2nd glance to see if i really am seeing something, well then it will still be there & then kinda takes off! Almost as if it knows I see & it wants me to. I find it very disturbing & aren't really sure what to make of it! Is it real or am I just some how going nuts?
