I visited a house of purgatory early in the night. It was a building the size of a city, containing a railroad that connected its halls. The halls were made of stone and lined with open arced passageways each leading into separate rooms. Inside many of the rooms were portals leading to different places in the universe. Other rooms contained souls in suspension waiting to be born (or going somewhere else).

The ceiling was supported by over 20 ft high pillars and embellished with with gold and green paint, but I couldn't see the ceiling well because my light didn't reach that far. There were no lights in the building. it was designed for visitors who didn't need external lighting.

The place almost felt empty, but I saw a few others wandering around.
Normally when I travel to any given location, there's a lot of people who aren't aware that dreamers exist. They don't know what I am and they assume that everything they see is mundane.
Not here. Everyone was aware. There were a lot of travelers like me, some of them had destinations, and others (like me) were just exploring the ancient building.

There were no entrances or exits to this building and not a single window or door.

There was a kiosk by the railroad where a seemingly empty shuttle would stop every so often.
There was nobody manning the kiosk, but I took the stack of forms that was left out for me and filled them out.
I was applying for the ability to pause my life and visit this place. I din't know whether that's was any different from what I was currently doing (lucid dreaming), but applied anyway because I figured time might not be linear (abilities I've had in the past could result from the application I'd fill out in the future).

I manifested a dream character who accompanied me for a while as I explored further and met people. I didn't speak directly to others (aside from my dream character), but we were able to communicate through shared consciousness. It was well understood amongst the visitors that separation is illusory, and this was the place where we separated ourselves.

I eventually saw everything I wanted to see and left through one of the portals, going to one of my favorite places (a beach!). I stole a cute little sailboat and pulled the boat into a private cove that I claimed as my own.
