The weather in Singapore had been particularly hot the last week or so. Hence utilities usage had been high as well as we would turn on our a/c just to cool down.
Because of the intermittent hot and cold temperatures i.e. from the weather outside , to aircondtioned buildings and such, I started to feel unwell and began developing a throbbing headache. As such, i stayed in at home to do my revisions instead of going out as i normally would.
As i sat down in the living room going through my notes with no one in the house around the bright sunny noon time, the musical wind-up snowman in my living room started to play for a brief moment - say abt 2-3 seconds.
While i was initially creeped out by the sound of the music with no one in the house, i realised that it was quite easily explained by science...
Try to explain this mystery if you can
