It is hard to interpret dreams and visions. Often they are like the red light that tells you the oil is too hot. It doesn't mean your engine is ruined, only that it is about to be if you don't do something immediately.Where is the meteor? These things can be seen years before they come anywhere near Earth
That said the best I can tell the meteor is behind the sun making it very difficult for any of our telescopes to see and will take about 14 days to hit the US once it passes the sun. If it is in the glare of the sun you wouldn't put a telescope on it and you wouldn't see it at night.
