I think id ghost it, but only if I could still touch and communicate with other ghosts or else id just be lonely. But I'd have fun for a while.
Sometimes people have unfinished business or they want to protect friends and family who are still alive.Also violent unplanned deaths seem to cause ghosts. Like people murdered seem more likely to stick around.
i suppose technically there's nothing scary about no ghosts. it's a plethora of ghosts that would freak me out.
There is a funny you tube video of James Randi as a ghost saying there are no ghosts . There are several kind of ghost . The soul of a once living person , left over energy , human created thought forms , astral critters , still living people asleep in there astral bodies .
why do they even have human shapes? answer: movies are movies. the immaterial do not require form. making them transparent is a way of trying to visually suggest this.
On ghosts in human form and with clothes, let's say one was good at astral projection and wanted to visit some one . While out of body in the astral one is the same as a ghost , just with a body to go back to . Any way you want to choose a non ghost looking form so you won't scare them.
