Dreams are an adventure

Family vacations were always something we looked forward too and we were doing something a lot more epic than usual. My dad had found a quiet town in southern Florida were we could just rent a house for a week for a very minimal price.
So, the first couple nights when we went down there were quiet relaxing days. Then things started to get weird. The kids got restless and we started playing games. Running games, hiding games, you know how kids are.
The townsfolk started to notice the energy we were stirring up and slowly started to leave. Not putting off vibes that they were annoyed but putting of vibes that they were scared what would happen if they stayed.
I brought it up that something didn't feel right and that we were vacationing in a ghost town. But my family thought I was just being eccentric.
Then one day I walked out of our little house we were renting and stood on the porch. Something seemed off. The air felt dry and stale, which was super weird for the coastal town we were in. I started to wander.
In kind of a marshy area about a mile from our house I ran across a tree house. It was epic in size and looked like it was put together in a hurry. I climbed up and saw brand new chairs and nick-knacks. Also there were bells dancing all around the exits.
It was so whoever was living here would have a warning before everything went to hell. The dead silence of the air was so uncomfortable I just had to find the source. Heading in a direction I knew felt most unsafe, I searched the swamp. I saw a group of people up ahead ( which was weird b/c the town had been empty for at least a full day). Slowly, hiding in the swamp I got around them to see how many there were and what they were up to. All I could tell is they looked like they were all bearing weapons and all of the members of the group looked like they had been buried for at least a year. Awesome, I thought to myself, theres like 30 Wights/Zombies in the most random place ever that we just happened to vacation at. They were odd to explain. Mostly because I knew they were dead and moving as a wight but I could tell they had physical bodies. I ran. As quickly and as quietly as I could and as I was running I ran into a boy, about 17. And man did he have a lot to say. He told me that the barn would be safe and that he was told if this ever happened to never leave that barn. The army was moving slow enough that we had more than enough time to get out of there. also I knew the family back at home would be packing and that they were going to leave a little after sundown. I knew I had time to get to them. Also, the army If they kept moving the direction they were going would just miss them. I ran with the boy to the barn he was talking about. And as I was running I heard a voice that said "don't leave that barn no matter what". We quickly ran down to the barn and hid under some lumber. Unfortunately the boy that was with me hid fairly close to me and despite the fact that I had found an amazing hiding spot he was jabbering on and on and would not stop. I knew it could give away our position but there was nothing that I could do to make him hold his tongue.

Now I'm not going to lie, I'm no writter so this next part may be difficult to explain. But imagine the best you can. We're hiding under some lumber in the barn and all of the sudden I hear heavy breathing. I try as hard as I can to smash myself to the wall and become invisible but the stupid boy's chattering ruined my efforts. Something black and light as a skeleton came smashing through th
