history: 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? I do!  It dates way back to pre-literate cultures, in the form of ancester worship or animism. Is it common nowadays for people to believe in ghosts?
