Dreaming in Plot Lines

I know there are people who say "I never remember what I dream" or "I always remember what I dream." I don't really fall into either categories. Usually I don't remember what I dream, sometimes I do. When I do remember, they're usually weird.

So last night I had this weird dream. I won't go into all the details, because they're still kind of confusing to me, but the dream did include: a Wal-Mart stock room that only seemed to stock empty paper boxes, Stormtrooper helmets, cupcakes, and pseudo bamboo staffs; a giant scorpion; an all powerful magical mask; Iron Man; and some kind of evil wizard or something. I know, messed up, right?

But at one point in the dream, when the giant scorpion unearthed the mask for the evil wizard/whatever, the strongest of the pseudo bamboo staffs ended up outside when I knew it needed to be inside for the conflict to come. In my dream I despaired about this fact for just a moment before my dream-self realized 'oh, this is going to be important for the plot later.'

That thought really stuck with me when I woke up. I don't ever remember having a thought like that in a dream before. What does it mean? I have no idea, but I just thought I would share.
