Ah, kids will imagine all kinds of things
When I was little my parents would always read me the story of the three piglets and the bad wolf. I swear I saw the wolf one night when I woke up in my room and he turned me around in bed. Sure enough, in the morning I woke laying upside down.That same morning while my mum was dressing me up for kindergarten, I saw the same wolf standing in the window staring at me. I even told my mum "Look mum he's here again" ..
Weird thing is I can't remember what my mum said to that, no matter how hard I try. I must have been about 4-5. I never saw him since ..
So yeah, I'd def go with kid's imagination..
