[NOTE: This article is based on opinions of Internet users and not facts.]\r\nBefore you start rolling your eyes, hear me out. Just because we wrote this post doesn't mean we're condoning any sort of superstition or belief in the supernatural. But hey, it's Friday the 13th and so, whether you believe in ghosts or not, just try to play along.\r\n\r\nJust remember, to a believer, no explanation is necessary; to the non-believers, none will suffice.\r\n\r\nWe trawled the Internet to see what people think are signs that indicate the presence of a ghost or a spirit around, and these seem to be some of the most common answers.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n \r\nWhat's that thing behind you? Slowly. Turn. Around.
