Oksana does this with one of her teaser things. If it's downstairs, she'll drag it upstairs in the middle of the night. I usually wake up when I hear it dragging, then she drops it and starts to meow. Then I call to her, she jumps on the bed and settles in to sleep. She'll do this also if it's upstairs. She'll bring it downstairs, then come to me to get a nice pet.
