Those who would call her a witch, it seems,,br> have forgotten some stories of biblical dreams,
of troubled kings and nasty drought,
and Joseph who saved them and figured it out.

Lady, you are completely out of your field. Having dreams from the Lord can be Biblical, however, consulting a medium (WITCH) is clearly demonic.

Was there a cult of the dead in ancient Israel? The Deuteronomistic legal material in the Hebrew Bible reveals restrictions against consulting the dead (Deut 18:9–11): presumably presenting offerings to the dead (Deut 26:14), and engaging in certain practices associated with death rituals such as self-laceration (Deut 14:1; but cf. Jer 16:6; 41:5) which seem to have been typical of Canaanite death cult practice. The Holiness Code also contains categorical prohibitions against people who turn to necromancy and demands the death penalty for any mediums or necromancers (Lev 20:6, 27)
