You have conflated two separate directions into one. Praying to God for, for instance, a deceased loved one or an ill person is one direction. Praying to a dead person to get them to intercede in some fashion is forbidden in Scripture. Are you familiar with the necromancy witch and Saul episode in which Saul sought an audience with the deceased Prophet, Samuel?

[Mark17]

Are you familiar with the necromancy witch and Saul episode in which Saul sought an audience with the deceased Prophet, Samuel?

That was an evil thing that Saul did. He dabbled in necromancy. It was evil, and it is forbidden. We are not discussing brain surgery here. It is forbidden, and it is evil.
