Dream About Life Or Death Manor Game

NIGHTMARE!..I had this dream before so I never expected this to happen again. This is my second time. And the thing, when l I woke up, I knew that this dream already happened. I remember all of it so vividly. It's very odd since I don't usually get nightmares, but when I do, I often forget them as soon as I wake up. So basically It's like a game, where there is an "It" and it's a life or death situation. So, I'm in a big mansion of the "It" I forgot the reason why, but I think it's the time where I was with someone, and we saw a stranger ALMOST getting kidnapped, so we helped that stranger and I remember the car of the kidnapper ran off, so we thought it was mission accomplished but no, the car started to make its way to us. So we ran, and that's how we got to the mansion of the "It", or so that's how I remember. I don't know what's the connection of the two but that's how I remember it. Going back, being transported to the mansion, we're with a large group of people. I don't even know the people I'm with but in my dream, I know them. We were informed to play the mannequin game, where we have to act like we're not moving once the timer starts. And if the "it" catches you moving, you're going to be killed. At first, there are already lots of people dying, I also had many times of instances where I ALMOST FREAKING DIED!#?#? Because I don't know why the heck was I moving places all the time instead of just acting like a mannequin. But maybe this is because I knew something will change soon. All I know is that I was traumatized as hell. But as the game progressed, the mechanics didn't apply anymore. (The "it" is a girl by the way.) It's becoming more like hide and seek, because once she sees you, she's going to kill you. Oh, her mode of killing is through gun. But the thing is, I already know the things that'll happen and yet, I don't know why I still feel like I'm going to die. Like, my heart's beating fast, I'm panting and everything. I already know the ending, but this time it felt like the ending is different. Because I already knew where the "It" would catch me where she'll almost kill me but the timer ends so I survive along with the other players. But no, during that dream I already have that in mind. I knew that this was going to happen, like this is a dream. But everything felt fast, the ending changed. I thought I was going to die, I already accepted my faith but no. Somehow, the timer ended. And we were freed, there were only five of us or probably more who survived. And that's when I woke up. OH and before this dream where IT FELT LIKE FOREVER!!
