Deep Inside The Lucid Dreamer's Subconscious

There was a before and after from this dream but it escapes me right now.

I'm in a game. I think my sister Abbie is there. In the game, you enter a room from the ceiling, from some sort of portal. It seemed like a light in a way but at the same time you could see through to the other side of the portal. The object of the game is to enter the room, find the object in the room, touch it (or maybe destroy it), and then return to the portal. When I got into a room, I had several other camera angles on the corners of my vision which would hint from another angle where this object was. It was sort of like a 3D maze and I had to go through it to find the object. The gravity seemed a little bit like water without having to hold your breath (even though you don't really need to in a dream). I would find the object, go to it, touch it, and then there were other players in the room that would fly into the entrance portal with me into the next room. It was a cycle, at the end of each round we'd excitedly fly towards the entrance and into the next room.

At some point, the portal drops me into this abandoned room. There's dressers and washer machines stacked up in the middle of this dirty room. A voice tells me that this round I have to find my way through. This scene is much dirtier than the other rounds. In the other rounds, the obstacles were crisp blue objects and the space was clear. This place seemed brown and toxic. And yep, here comes Pennywise the dancing clown again. He pops up from a washer machine in the back of the room. He starts to run at me, moving washer machines and dressers aside. He starts to grow larger and larger as he runs towards me, we zoom out of the house and I realize I'm on Owen's street. I'm not sure what happened next.
