When we moved into our new house, a few odd things occurred that were tough to explain.......at first. 1.) After a few months in the house, I was sitting on our bedroom floor, watching tv late at night. A silver orb floated down the hallway, and then dissapeared into the dining room. I honestly about crapped. I sat there a while, and it happened again. I got up, walked down the hallway into our darkened living room, stood, and waited. Sure enough, as I stood there, a car came around the corner, and as they went up the street, the headlight hit my front bay window just perfectly, and sent a silver ball of light up my hallway on the wall, til the car passed my house, and the orb 'dissapeared' into my dining room. So several months later, I'm again sitting on the bedroom floor in the evening, when the bathroom door licked shut. Now this is a hollow core door, so it swings easy. It's got a good doorknob/jamb so it does take at least a minimal amount of force to make it click shut. I got up, investigated, found no reason the door would shut. I open it again. Once the fall came, and heating season kicked in, we leave the bathroom door open a crack because there's no exterior walls on teh bathroom, and it gets hot as h-e double hockey sticks in that room. So about an hour later, the bathroom door shuts again. Now I have an idea of what's happening. I get up, open the door about 4 inches. I turn off the furnace. I wait a few minutes. Turn it back on. Turn the thermostat up to about 75. Sure enough, when the heat kicks on, the register in the bathroom has just enough gusto to shut the bathroom door softly. Now, I've seen these "ghost hunting' shows a few times, and I honestly think 98% of what people think are ghosts are crap like what I found that can be easily explained if you take a half hour and do a little investigating.
