My logical side says no but an experience I had when I was 9 or 10 makes me think that maybe they do exists.. When I was a little kid there was a "haunted house" near where I lived. Actually all that was left was just the foundation and fireplace tucked into the woods that had been long overgrown. I don't know if it was true but the story was that some crazy old man had lived there and one night was getting drunk and threw a nearly full bottle into the fireplace resulting in the whole place burning down, killing himself in the process. Folks said he haunted the place.

Every now and then we'd go to check it out and one time as we were walking up the pathway through the woods to the place me and my friend both saw something. Kind of like smoke or fog roughly in the shape of a person that didn't seem to disapate. We didn't stick around to see what it was and both hauled ass out of there and never went back.

For years I swore we had seen a ghost. Who knows, maybe there was some tokers nearbye who had just blown out a big bong hit and we just thought it was a ghost. Whatever it was we did see something. I'm a bit more skeptical now but I sure as shit aint going to say it's not possible that it was a ghost.
