I also once a heard a woman's voice at night. But she didn't sound like she was coming from a Radio. This was in my old house that I moved out of about 3 years ago. The extra room we have that was my room on different occasions became a study room where my sister's computer was. I was up late installing windows xp on it for her and was waiting for it to finish so I put my head down. I t hink it was about 2am. Anyway I suddenly hear a woman laughing and nobody was home, nor any appliances on. I got up and walked peeked around but saw no one. Needless to say it kept me awake but I was still tired so I put my head down again. *laughs* My most haunting experience, though not necessarily scariest, was in that same room when I was about 14-15. About a decade ago. I was up late watching a special on Discovery channel about mythological creatures in modern times like Bigfoot etc. It was especially creepy for some reason. Especially the Bigfoot part of the show because one of the sightings told by a person spoke of how he was deep in the woods setting up cameras and the like for a long time trying to catch a picture, when out of the corner of his eye he saw what he thought to be a set of eyes staring at him through some undergrowth. And of course the show reenacted the scene and it was all very creepy with mood music and creepy narrative. The man was frightened and believed it was Bigfoot stalking him. In any event I went to sleep a little nervous getting into the show so I had some trouble sleeping but eventually I began to doze off, with the covers up to my eyeballs. Gradually fading away into a sleep, you can remember the moments just before falling asleep while you're not fully awake but not fully asleep... it feels a little dizzy and your body starts to feel heavy. At that moment just as I was about to crash... the front end of my mattress swung upwards and back down in less than a second. As if a person was standing there and lifted it with their strength and let go immediately. I got up terrified with my eyes wide open, turned the lights on and stood in the center of my room doing a full 360. Checked my bathroom, checked the next room, the kitches on the opposite end. I stood there for a while and went back to bed with the lights on.
