Last year I was tracking Santa most of the night, and around 01:20 am Christmas morning (when I was in bed), I heard the sound of a sleigh bell in my bedroom!
OK, it sounded exactly like a bell from a cat collar, but my initial thought was 'sleigh bell' ...
... and I no longer have a cat!
I still haven't found an explanation for me hearing the bell. I wasn't asleep or dreaming, as I'd only been in bed for 15 minutes!
Going to my school was an education in itself. Which is not to be confused with actually getting an education (Schultz)
