Does God acknowledge ghosts?

I'm reading the Bible for the first time. Deuteronomy 18:10 states "Let no one be found among you who sacrifices his son or daughter in a fire, who practices divination or sorcery, interprets omens, or casts spells, or who is a medium or spiritist or who consults the dead." Is that an acknowledgement that the dead CAN BE consulted? What does the Bible say about ghosts?
