“A flashlight is a ghost trapper’s sidearm. Seriously. You can chase a lot of nasties away with a solid blast of bright white. It doesn’t hurt them, but it can bother them enough to make them slip off in search of darker pastures. A strong bright light interferes with the ghosts’ electrical fields, making it harder for them to focus when they want to claw at you or throw dishes at your head. This is probably why ghosts prefer to do their haunting and harassing at night.”
