As William pointed out, for the serious Christian, many of the things discussed here come from the "dark side" of existence:
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' 1
0Let no one be found among you who sacrifices his son or daughter in
a the fire, who practices divination or sorcery, interprets omens, engages in witchcraft,
11or casts spells, or who is a medium or spiritist or who consults the dead.
12Anyone who does these things is detestable to the Lord, and because of these detestable practices the Lord your God will drive out those nations before you.
13You must be blameless before the Lord your God. (Deut 18:10-13)

Saul decided to visit a witch for "fortune telling" and lost any chance he had at salvation;
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' 7Saul then said to his attendants, “Find me a woman who is a medium, so I may go and inquire of her.”
“There is one in Endor,” they said.
8So Saul disguised himself, putting on other clothes, and at night he and two men went to the woman. “Consult a spirit for me,” he said, “and bring up for me the one I name. (1 Sam 28:7,8)

Saul KNEW this was forbidden, but he defied God and did it anyway;
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' 10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch.
11 Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer
*.
12 For all that do these things are an abomination unto the Lord: and because of these abominations the Lord thy God doth drive them out from before thee (Deuteronomy 18:10-12)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' * A necromancer...one who "talks to the dead"..as in spirtism etc.
