The most frightening vision I've ever had

[Rfrost]

So, I had this vision a long time ago, but it keeps coming up.
Its really, really scary.
So this took place right after the really bad tornado that hit Moore Oklahoma.
I was in a basement, it was pretty big.
It kind of looked like some place for storage.
It was absolutely flooded and it was nearly pitch black in there.
The only light that was seen came from two doors, one as the entrance and the other as a back exit.
There was debris everywhere, and bodies floating in the water.
Men, women, children, dead.
Then they all opened their eyes and one by one started to slowly get up.
I feel backwards on the stairs trying to run away, then I noticed there was someone behind me.
And the vision stopped right there.

What was the scariest vision that you have ever seen?
