Zombie games

I put it in dream help since I want more of these dreams since they're scary but FUN

basically this is My sign I watch too much Squid game:I got a dream where all of my school was in a miniature archipelago playing till only one survived,the first event was fighting against zombies that fell from the sky and I almost died but I took someone that was dead's knife and started first killing zombies and then when everyone started fighting I started stabbing everyone I could going on a 333 level rampage LOL.

Then I was about to die since someone stole my knife but the event suddendly stopped and everyone was brought by guards to a while hall full of rooms without doors or hinges to team up/go solo before they would've shut off the lights and encouraged fighting between the 60ish survivors counting me that were left,I teamed up with two friends and many randoms but right before the battle started I woke up

Also somehow gravity was like 1% weaker and time was slowed when I needed it?
