I have dreams all the time where nothing is quite the right size. Or at least not the right size all the time. Kind of like the Foo Fighter's video for Everlong. Ceilings are too low, or the car seat is pushed impossibly far back. People are often the wrong height, sometimes by several feet but they can return to normal size in a blink.

Most of the time I don't even know things are weird until after I wake up. But sometimes I *do* realize inside the dream that an attractive woman is 7 or 8 feet tall, and I try to "keep" them that way but I almost never can. They'll randomly/suddenly be normal-size without shrinking, like they had never been big at all. Yes, it can be frustrating.
