We used to have an army training grounds not too far away from my place which would use the cannons in training. So one day when I was 5-6 my brother told me that the cracks in the black footpath were the footprints of monsters, and the bombing sound the army made was them stomping around the neighborhood.
I used to be happy when I would hear the cannons, glad that I was inside, and I would look out the window trying to see the monsters.
