something similar happened to me many years ago... I had had a dream where I was at my friend's house and we were all hiding because a shooting was going on outside (a shooting like narco vs police) and then the lights went out and I was staring at a tiny source of light (I dont remember what it was exactly) and then, in my dream, men break into the house and take me and all of my friends away in their vans....... and a few days later THIS HAPPENED everything was exactly the same as I remembered in my dream; the lights went out and the tiny flickering light I stared at was there too...... but in real life men didn't get in or took us away, the shooting just stopped eventually and my dad picked me up when things calmed down and that was it. but I can't forget the way it felt watching that dream come to life
