What Are the Most Common Evidence of Hauntings in Your Home?

Reports of lights flickering and electronic equipment turning on and off on its own, even when unplugged, is common. Other people report more physical activiti, such as doors opening or closing, lights or t vs turning off by themselves. We've had a lot of reports of sterios, radios turning themselves on when they're not even plugged in. It's funny to me how much like everything that was just listed, except for the unplugged part, is stuff that would be pretty much perfectly explained by the physical effects of a storm.
