Dream of roof

There are many slides. It's dark but the slides are rainbow. When you slide down one, you enter a ball pit. When you go under the pit, there's a lake. Things move slowly, people on rafts. There's a cave at the end of the lake. There's a hole between the wall and the floor. There's a re-occurring roof. There's also a tiny door that leads to a weird basement that's scary. There's also a scary house, where the rooms lead to more rooms, until it leads to the scariest one but I never get far enough. There's a maze. There's a forest. Family members. I fought someone with knives. I jumped into a freezing cold lake. There are a lot of giant waves.
