You went ghost hunting hoping to find ghost. Duh! Are you out of your mind? Of course you start seeing things. You already prepared yourself to see it even before embarking on the mission. And you see things the slightest things you suspiciously say it is haunting. If you see a monkey that night you will say its haunting. If you see bats? You will probably thing the Count Dracula is somewhere in the vicinity. You go looking for something in the Mathilda House. Its empty, its dark, of course you will feel scared and spooky. Because it is empty and dark. Stop making stupid stories like this to scare people about Punggol. There is no ghost in Punggol. If there are, its all in your brain, you created it!
