Unfortunately, my laptop is temporarily out of commission, so I don't have access to a few of my notes for the past week, but I'll get back to them. Here are the ones from Monday morning, though.
I was with a group of people, exploring a vast, underground cavern. It was maybe half the size of a football stadium / dome, and loomed over a massive body of water. At some point, I remember that we were hanging from the ceiling, though I can't remember how we got up there. I can only recall that we were trying not to fall in the water, due to the notion that there was something large and deadly living in it. (Possibly inspired by reading a dream of OpheliaBlue's that referenced huge, underwater beasts, recently).
I was talking with an apparent 'girlfriend of a friend' (though I don't know who), about her "superstar" ex-boyfriend coming to town, soon, and her wanting to go to dinner with him and catch up, despite being in a relationship with my friend. (A topic of conversation, that came up, a couple of days ago.)
