Nightmare Fuel: Ghost Stories
The original invokes this (or attempts to) and builds its appeal around this. The ghosts of the later episodes are noticeably more menacing and scarier, to the point that some viewers are surprised that it's made for children. The Gag Dub, of course, isn't as scary as the original, but the character designs and paranormal vagaries are still present to unnerve the viewer.
