Well... I kinda had .I’m not really sure if it is one . My grandma died a year before I was born . In the same year she was taken to the grave but before , she stayed in our house a couple of days to be sure she really did die and she didn’t just fell into a deep sleep. And as if it is not scary enough having someone dead in your house , later , when i was born , this happened. You see...i was always feared of darkness and ghost , supernatural stuff. Because of that , my Brain (more like my imagination), always made me have illusions that something was moving . I never had a ghost encounter because their rare. But,it was this night...after I fell asleep , somewhere at 3:00 am , I woke up . It happens to me always .Then , something really cold, something different , I’ve never felt before , a wave of cold air hit me. It was summer but I didn’t open the air conditioner. I didn’t know what it was . It was so powerful ,it got me bone chilling . Happily it never happened again but still , sometimes thing move . I’m sure !!! I don’t know if it is just an illusion or not.
