The restaurant I worked at in Hingham supposedly was haunted, but I never had any direct contact with any ghosts. I used to have to close the place up at night by myself, and enough people, who I gave some level of credit to, had spoken of having some ghostly experiences there that I was definitely a little spooked. To the extent that I was feeling spooked at the prospect of there being a ghost, I guess I believe in the possibility of their existence. But I think without any direct first hand contact I'll never fully believe, no.
