Perfectly Normal Dream, Nothing to See Here

In the latest of my utterly bizarre dreams, my sister and I were some sort of demon fairies on a mission to do some magical gobbledegook for official End of Times business.  But we looked exactly like regular people, except for some flickering behind the eyes.  In order to complete our business, we required a safe space outdoors or a room with a large south-facing window.  We also required lots of food.  The other equipment we already had.  Unfortunately, due to other official End of Times business, outdoors wasn't really shaping up to be the best workspace with 70 mph wind and sinister green sky, and we were deprived of the necessary funds to legally acquire a room with a large south-facing window or lots of food.  Fortunately, since it was the End of Times, we didn't figure these hurdles were that important.  So, as we were walking around looking for suitable spaces, we casually stole the candy and snacks and so on that people keep in opportune places.  We went into a hotel and magically unlocked random rooms to see if they were suitable.  They generally weren't, until we came to the pool room attached to a large lounge area, with floor-to-ceiling windows on three sides, including south.  It was perfect.  So we set up shop on an unoccupied couch near the corner and got to work--we had a contraption to set up to facilitate the opening of a Mystical Portal, which was probably going to rain fiery death over the land, or else let in some immortal ruler, who knows?

The only drawback from our perspective was the friendly humans.  You see, friendly humans can get curious about and interfere with demon fairy business, and if they get too close, they can recognize us, or just get contaminated with demon fairy magic and spontaneously combust.  And humans nowadays are trained to recognize when they have been contaminated; it's a public health mandate.  So, some random girl comes over from the other side of the room to see what we're up to.  She pokes around for a bit.  She says chatty things.  She eats one of our cookies.  She gets contaminated.  She realizes what has happened, recognizes what we are and that we're probably up to no good, and does the only sensible thing--she breaks through a window and runs out into the howling wind in search of a fire hydrant.  We see she is starting to glow on the edges.  Now everyone in the room is staring out at her, and at us.  We try to blend in, staring around in mock-confusion and fear, but we also pick up the pace with the portal contraption.  As soon as another human gets up from his table and starts walking in our direction with a less friendly look on his face, all bets are off.  We cram as much energy into ourselves as possible in seconds, littering the floors with candy wrappers.  My sister melds her hands into the portal to complete the necessary spells, while I get up to intercept our visitor.  I don't want to hurt him or contaminate him or anything like that.  I just want him to leave us alone long enough to welcome the demon overlords from beyond the portal.  Is that so much to ask?
