Doesn't sound fun at all.

How did you know you were over the bay if you were inside? Does any of it make you think of anything; doesn't sound like you knew the men and the situation was certainly surreal so it's probably about an ongoing issue you're dealing with personally. I'd look for ways I felt trapped or that I was blowing out of proportion (like a ballon) or ways I was behaving/things I was thinking that made me feel like "throwing up" because I didn't agree with them.
