travelling through the pipes

We were standing in the shower of a bathroom, in a downstairs unit of an old apartment block. Somehow, we were to travel up through the pipes to a unit upstairs. We sent some of our belongings up ahead of us and then we entered the pipes, shot upward and emerged in the shower of the designated apartment. This shower was above an old, pink enamel bath, enclosed by a plastic shower curtain. I hopped out of the bath, thrilled that our journey had succeeded, and waded through the items we had sent before us, which had spilled out of the bath and over the tiled bathroom floor. I opened the bathroom door, about to walk into the living room, but I heard the television and realised that someone was home. I quickly closed the door and ushered B back into the shower. I collected as many of our things as I could and jumped into the bath, closing the shower curtain around us. Through the curtain, I saw a young man enter the room, having heard us trying to get away. He glanced at our remaining things lying on the floor, walked straight over to the bath and grabbed the curtain in his fist, about to wrench it open. We held it closed and, although we could see through it and watch his response, he could not see us. I called out: Please don't open the curtain, I'm simply having a bath. He retreated, but said he would be back. B and I tried to send our things back down through the pipes, desperately trying to recall how we had morphed to fit in ourselves. Through the curtain, I could see the man. He had closed the bathroom door behind him and was again approaching. Suddenly, it worked. The pipes received us, opening up like a tunnel or a black hole. We travelled downward and, soon, B and I were back in our own unit, again standing in the shower, surrounded by our things.
