Underground, Rave, Church.

The content doesn't make sense, like usual.

There is some forbidden door. There is myself, and two more people. I think it's my older sister and someone who I know. We walk through the door, and it leads down long stairs.

When we get to the bottom, we enter what seems to be a large underground sewage system, just without all the smell and crap everywhere. Very clean, stone or cement walls. We hear techno music coming from somewhere. Possibly an underground rave going on somewhere. We can't quite point out where it's coming from.

We can go either left or right. We decide to go right. A hundred or so feet later the path splits again: left or right. On the right, there is a very wide set of stairs going up. We go right. Once at the top, we hear people talking somewhere on the left, we follow the voices.

When we reach the source, we observe some ceremony going on. It appears to be religious. Perhaps a church gathering.

From here, something strange starts happening. Don't remember what.

The rest of the dream is lost.
