Maybe a good place to look , especially since you were "Through the Looking-Glass" in your dream (banging on the glass doors), and the Red Queen (even though it was a faceless dude! lol) moved swiftly away from you. It seems, Alice, that your subconscious is trying to tell you you're not out of Wonderland yet (maybe even for just one particular instance or delusion that still remains). Maybe the swiftness of the closing of the mall means you have far less time to rid yourself of whatever delusion you're holding onto before you can't get out.
[]Good luck! and please follow up if you have any other related dreams or real life stuff happen.
