This was the 3rd time I had a dream about it... and it was so real. I'm still shocked about the enormous size of the incoming, rotating, fast closing, unevenly shaped planetoid, and the quick finish of our lives after that. I was at the sea, far out from a cruise-ship. 1st I said: 'Oh my God, where did this come from?' Then for a second I thought let's hurry back to the ship to be with the loved once in the final moments. But I had to realize that the time is not enough. Just wait for the end which came super-fast. Huge explosion behind the horizon, the sky in flames, flying mountain-sized rocks, a huge evaporating raising wave of water and a second later a shock-wave which blew us away and burned us apart in no time. There was no chance to escape, no pain to feel, just the "gift" of the last incredible moment of our life. And peace.
I don't remember about the first dream, only the second. That was kind of similar to this, although a bit different.
