I think it's pretty clear
0) Being in a ruined building
1) Running floor to floor
2) No color, only chalky dust
3) No sound or motion
5) Mangled bodies, particularly heads and torsos
4) A burned baby (innocence)
Again, this was the very night before the attack, and I mentioned it to my date, something I don't do on dates (i.e. talk about my own dreams). It was the chalky dust covering everything that was the spookiest, because that was only made possible by the pulverization of the concrete floor slabs in the towers. An ordinary catastrophe doesn't produce widespread ashfalls.
And again, it would not have been possible to correlate this with the actual event beforehand. It's not like the dream is a video of the coming event.
A similar thing had happened about a year earlier. In the dream, I hear an airplane in distress approaching closer and closer in a dense fog - I can't see it but then hear a deafening explosion. A few days later, the governor of our state died a few miles from my house in a plane crash in heavy fog and drizzle, and the description by witnesses matched the dream exactly.
A prophet? Of course not. But a lot of weird stuff seems to happen to me.
What's the explanation? For one thing, time is evidently not what we naively assume. For another, there must be some way of symbolically perceiving the future, even if we can't see it like a video. For months before the attacks, I would be looking at the buildings of downtown St. Louis and imagining what would happen if an airliner plowed into one. I could not understand why these thoughts kept spontaneously popping into my head. The airport is well away from downtown, the highest building is only about 650 feet, and there is an infinitesimal chance of an airliner hitting one. Once there was a very loud noise downtown, and I looked up at the Mercantile Bank building for the hole I was sure I would find - it was nuts. For months before the attacks I was extremely edgy and startle-prone - since the attacks I've been my old self. I can only interpret this to mean I "knew" what was coming even though of course I was not conscious of it - nor could I be in principle, I think. It's only afterward that you know, and that is the strangest thing of all.
