I do!  It dates way back to pre-literate cultures, in the form of ancester worship or animism.
Do you think it was someone who actually once lived, from the afterlife?  A manifestation?
hey do you think ghosts exists? Hmm I don't have that information here right now.  They've been described as being translucent or even invisible, as I understand. Yes.  But I think I've heard of other sorts of descriptions, too. Hmm yes.  The've also been described as wispy shapes or realistic and lifelike! Cool!  I wonder how long people have believed in ghosts, do you know?
The belief in the existence of an afterlife, as well as manifestations of the spirits of the dead is widespread, dating back to animism or ancestor worship in pre-literate cultures.
