I also had one or two notable personal experiences with no evident rational explanations. Like a window to somewhere briefly opened. One thing I know for sure: You can’t MAKE them happen, no matter how hard you try. They happen when they want to (or when God sees fit).
My family never believed in ghost up until we built a new house in 1982. It never crossed our minds until we moved into that house. The entire family, extended family, friends and neighbors have had unexplained things happen to them in my parents house. Beds shaking, items disappearing and reappearing in weird places, crashing sounds in the kitchen in the middle of the night that wakes you up to find nothing amiss, doors that open and close and you hear people walk in that room, glimpses of someone passing by the corner of your eye, full body apparitions, on three occasions three different family members held down in their beds, you turn the light off, lay down and within seconds something slaps the pillow right next to your ear and you can feel the air from whatever it was on your face.
Before we moved into this house no one in my family believed in ghosts or the like. Parents, siblings and their spouses and kids, aunts, uncles, cousins and their spouses, neighbors and friends all having weird things happen to them. The house was blessed when it was built and other than the three family members who were held down in their beds the events were more mischievous than anything. I have offered to set up a camera and my Mom will have none of it, she says, yes I know something is here but I don’t want to know what it is. My wife and I briefly lived with my parents when we got married for about six months. When we got married I told her things happen in this house so don’t be surprised and she blew it off as nonsense. One night about 2:00am she went to the bathroom and walked out of the bathroom and she looked toward the kitchen area and saw half of a man from the waist up standing there barely visible from the night light my Mom left on in the kitchen at night. She tore down the hallway into our bedroom, slammed the door and locked it and jumped in the bed shaking next to me.
After being there nearly forty years most of us have become used to the happenings and my parents will note when something happens but don’t get excited or concerned.
