I saw one in my apartment in Warwick when I was younger. My dad was out of town so me and my brother were doing his paper route for the week and we had to wake up at 3am to go do the job. One night I was sleeping on the couch and all the lights were out, and I saw a person walk in to the living room where I was and they were standing behind the couch just looking over at me. So I sat up and said "Is it 3 already?" And turned the light on and when I turned on the light they were gone. Afterwards I got the most intense feeling of dread I have ever felt in my life and I stayed awake with the light on for the rest of the night lol
