There were a bunch of people digging a long tunnel which happened to end (for now) under my house or office. There was a hole in my wall where I could crawl in, and I found a rope just barely long enough to lower myself down into the tunnel. I met a girl down there and she came back up with me to visit. She was cute and had long orangish hair and told me she was from Ireland. I took that to mean that the tunnel went all the way to Ireland, which I was very impressed with (before she told me that I had assumed the tunnel was from somewhere closer, like New York).

This all reminded me of a similar tunnel project in China, except the people there were being forced to do it instead of doing it for fun.

Later I went back down with CJ, and now there was a train going through the tunnel. I was trying to jump back up into the ceiling (the gap there that led to my closet was narrow enough that one could push themselves up without a rope), but was having a hard time with it.

Later in another dream, I was with a group of people heckling some shop we didn't like. I was stringing some ethernet cable up some steps to somehow assist with this.
