What could this dream mean?

I had a very vivid dream last night, and am curious as to what it could mean. In the dream I was looking out a window to the east, it was 8:47 in the dream, in the morning but I think the sky was dark so it may have been night. In the sky I saw a blue glowing ankh, then I heard words, “he is cast down to earth” from the ankh there appeared a blue ring that show from the sky and landed on earth. In the dream I was very distressed and knew that Lucifer had been born or cast down if you will to earth. Then I was at a bar and trying to warn people, but I couldn’t. I bought a phone or something for 280 dollars it was supposed to be 480 but for some reason there was much commotion and I got it for less. Also there was a girl in a red car, I correlated her with evil and helping the devil. That’s about the gist of it. What do you think it means. Please not the 280 and 8:47 add up to the number 10 whereas 480 ads to 12 or 3.
