you are walking to the park because you just left your home without your parents knowing , you sit down on one of the swings and then you start playing, it’s 9:00 at night and the park looks empty, you start to think to yourself “hm the park is usually more crowded, is there someone out here?” you get a strong feeling like someone or something is watching your every movement, you are looking everywhere, one even the entire play place,“nothing”, then you look behind you.
