I'm in a school-like setting - white walls, plain furniture, and ordinary tables. Off to one corner of the room is a closet with a shelf just above head-height, where I am arranging some things. At my feet is sitting an expanding file folder.

I look up to arrange something on the top shelf for just a second, and suddenly my laptop computer is gone. Just to my left is somebody who is messing with a soft bag on the top shelf, and I can see something flat and rectangular in it, the shape of my laptop.

Really quickly I step out into the room and summon a security guard, asking him to look in the bag and get my laptop back. But now there is nothing in the bag, and my laptop is nowhere to be found.

I keep looking again in the area where I lost it, and cursing that I let it get stolen. It was my nice $600 touch screen laptop, and now I will have to use my older HP one for school.
