Ok, I had perhaps the most over-the-top, WTF did I eat the night before dream last night:
It basically was framed as a Die-Hard movie. It was one of those ones where you are the "hero" and see your actions both from the first-person and third-person.
Anyway, I (John McClane) am pursuing this evil mastermind, and the events of the dream happen right at the ending denouement scene. With my daughter and another male cohort (who may or may not have been romantically involved with her), have tracked the main bad guy down to his headquarters -- a weird shopping mall-esque building (which is the front to a more sinister operation). In this mall, people from off the street and from other businesses rent out space to sell their goods over a sprawling, multi-tiered show floor (kind of like an indoor version of an outdoor market). BUT, underneath it all is a vast, deep chamber, the size of that enormous chamber in Empire Strikes Back where Vader reveals his true ID to Luke. Lining this chamber were walkways with doors leading to . . . something nefarious (computer servers, drugs, WMDs, who knows). And in the middle was this giant, skyscraper-like tower (true purpose also unknown). Anyway, I, my daughter, and other guy somehow get on top of this tower thing, and I know I have to (of course) get all the way to the bottom of this chamber, but time is running out before . . . something bad happens, so I know I can't take the normal elevators/stairs. Besides, it wouldn't be an action movie if I did something so mundane, so I shoot this incredibly long grapple line to the ceiling (which at this point isn't that far way) and start to slowly climb down. The others are find to stay there until bad guys, along with the main bad guy start pouring into the chamber and attacking us. Daughter and other guy start climbing down with me.
Somehow we all wind up on different platforms of the chamber, fighting different bad guys.
Something else about this chamber . . . it is built into the bay/sea-side, so there's water all around us, kept out by huge glass windows.
Anyway, there is a gigantic explosion outside of the chamber windows (cause unknown) and the blast comes bubbling toward us, and we just know the window will shatter. We all scramble down to the chamber floor just in time to see the blast wave hit and shatter the window, tons of gallons of water pouring in, slowly filling the entire chamber.
We eventually just decide to stay put and let the filling water carry us back up to the top.
Dream ends there.
What was in that underground complex? What caused the explosion? Did we all survive?
Ugh I wish I knew
