I was visiting my family. I arrived and everything seemed normal, except that they were in the city where we all used to live before I moved to another state, it's a calm, sunny, tropical place.
We were all happy and excited to be together (I get to visit them every year or two). We spent the day doing normal family stuff, and later on my father told me to use his motorcycle to go on a ride, see some friends, or whatever. I got on the bike and thought of seeing some old friends in that town but I got too caught up on the road, going everywhere and nowhere at the same time. Later at night when I was on my way back, there was a sudden flash of brightness, it wasn't just in fron of me, it was everywhere, all around, so I had to slow down, and right after that, something happened to the motorcycle and it broke down in the middle of a big avenue. Since it was dark and I didn't have any tools, I wouldn't be able to fix it right away, so I just left it on the sidewalk and locked it then walked to my parent's house. I got there when everyone was asleep so I had to be quiet. I was tired from all that happened the night before, and I figured I could get up as soon as the sun started coming out, grab some of my father's tools and try to fix it myself, either way it must've been something really simple and with enough light and time I should be able to get it going with ease. I was getting there and I received a call from my father, asking where I was and etc, I explained and he said he'd go take a look at it himself, and that we could go get some food after. I agreed. And this is where things start to get weird. After a few minutes, again I got a call from him, saying that he was just around the corner, in the car and with the rest of my family, which is mom and my three sisters, and that the car had broken down too, then the call started fading away, cutting off. I saw him walking down the street and we took a look at the bike, but no luck, after a while, we noticed there was something very strange around, it was already at least about 8:00am and there were no other cars passing by, no people walking, no businesses opening, no noise whatsoever. We decided to leave the bike and walked a few blocks down to where the car and the rest of my family were. Everyone had noticed the unlikely calmness of the day, and the absenceof people. We tried calling anyone, friends, relatives, even the police, but the cellphone reception was getting worse little by little, first it would give you a dial tone and cut off out of nowhere, then it would just make this loud, high-pitched sound and turn off. We weren't talking much about the whole thing, trying to have faith in a rational explanation for whatever was going on. We kept on walking. It had been at least an hour and still no sign of anything around. We were around my grandparent's house and we decided to go check it out hoping they would be there or something. We got there and the whole house looked completely different, like it was turned into some big company's office, the windows were sealed, the garage door reinforced, we tried somehow looking inside but even the wall-fence around the house was taller now. We eventually gave up. We kept on walking. For hours straight. It wasn't funny or cool at all. I could see my parent's faces full of anguish, not knowing if we were safe, not knowing if we'd find anyone at some point, and when. !!! I had a lot on my mind too, I was stressing out about water and food, thinking about the possibility that the water would be contaminated, or not, and if it was going to be easy to get food, stuff like that. But we kept on walking. All day. The sun was starting to hide. And there, on a highway about 2-3 miles away from a set of the fancy type of houses, my phone started vibrating. All it said was 'keep going; you're almost there' and then it turned off again. We followed the road until one house became specifically noticeable. It was the only one with electricity in it. It had very dim yellow and soft purple lights on the inside. And between the silence, there was this noise gradually getting louder as we walked towards it (pause here, a few days ago I came across this, which describes the kind of noise pretty accurately: https://www.youtube.com/watch?v=JSASzFWEa84). It sounded and kinda seemed like a party. The house looked expensive, the kind of house with a huge swimming pool and a terrace outside. People started to come out to the upstairs terrace then eventually some gathered outside the house too. They all seemed to ignore us. Then this guy came out from upstairs, with a gun on his hand, and started yelling something about himself owning everyone in that place. He looked a little under 30 years old, white, with short hair and a tattoo on one of his arms. People seemed to ignore him too. Then he started shooting anyone that was around him. He eventually came outside. He seemed covered in pure rage. The people around were screaming, some would try to crouch but they wouldn't run away, and the man would eventually reach up to them. He killed everyone at his “party”, some of them with a clean shot through the head or the chest, and some others with a few shots, first the legs then the rest of them even though they had dropped dead already. After killing all his guests, which were around 15 people, he was outside of the house and he stared directly at me for a moment, then put the gun in his mouth and killed himself. I was more than shocked. Right after that, all the lights in the place started turning off and eventually we went back to the road. I could barely think of anything else but the guy's stare, and how he viciously killed everyone there. It was completely dark by then and the dream just faded as we kept on walking.
