We had just gotten done being intimate , and I was in the bathroom , she was in the room . The moment I went to grab the door , I heard a voice (in her voice) say “oh?” , and I continued walking in the room and asked “what?” . My girlfriend looks at me and says , “that wasn’t you?” , and at that moment a shot of pure static flows through my body and everything stands on end. We systematically pulled the house apart , looking in closets and under beds , completely freaked out that we both heard something that clear. She told me she heard the same thing , but only in my voice. Neither of us said anything. I’ve had paranormal encounters in the past , but this was the most cold my blood has ever run in something like this . The voice was unsettlingly similar to my girlfriends and clear as day.
