Story Today I had a strange dream (prophecy?)

[MelaninQueen]

Today I dreamt about a town that looked like Syria and Southern Turkey at the same time. I saw meadows and olive trees... but I noticed a group of men with black robes and horses with black banners riding along the place. Then, I heard a really loud noise (it sounded like an earthquake). I ascended into a hill and I saw a large army heading towards the town I've described previously.

What could it be?
