Why?

9/11 ... Sigh. I had a strange dream the night before It happened. I was looking at that kind of art kids make from cutting and pasting different colors of paper to a board. I saw a dark rectangle in front of me against a lighter background. Then something ripped a big tear across it, a bit above the middle. I felt bad enough the next day hearing what happened, but especially creepy to see that footage of one of the planes tipping sideways and leaving that big gash in the tower.
