You was in the middle of a light doze when you hear a noise behind your house. You decide to take a look but then you saw an unfamiliar town with a strange dweller. As far as you know, there's no such a town behind your house. Being the curios of you, you saunter slowly toward the kitchen that connect to the backyard and peek at the window. Instead of trying to found out about what had happen, you feel like someone is watching you from distance. 

Who's actually the person that looking at you and what with this sudden town behind your house?
