I had a dream once I was at my grandparents house standing out on the front patio (during the day) and I saw something like a black hole pass by in the sky from east to west. After that I went inside and I remember hearing some kind of emergency alert on the radio (can't remember what exactly) and then a family member said "Oh God. It's happening." I remember looking out the window and seeing this giant orange wall of fire (or something) approaching like a shockwave and knowing I was about to die. Then I remember what I believe was another viewpoint of the same event from space. This celestial body passed by the earth close enough to graze the atmosphere, and afterwards I saw these bright orange auroras light up about a third of the planet. I don't remember anything else.
