We all come here to fill that dark urge, to be "creeped out". The sensation makes us feel alive by prying at our primal instincts, the ones that kick in when we are cast far from our comfort zones. Though, with us being human beings (mostly), we all have a different experience when it comes to this sensation. For me, being creeped out is when you are overcome with thoughts of the unknown. It creates a sense of desperate hopelessness and weakness, because you know there is someone or something out there that is poised to strike, or maybe just studying you, and there is nothing you can do. You don't know what they, he, she, or it wants with you, but your mind automatically turns to the worst case scenario.
These are my thoughts on it. What's your definition of being "creeped out"?
