For conversation with the dead go to a cemetery;avoid the grave's Annoyance, speaking always gently:
"Earth bone, And winding sheet, Let this spirit Come to me- Yet send it In peace Or not at all."
If it comes, it should be offered white wine not red; and knelt to from pity.
Think about your last spell, hex, curse, whatever you did last how it went wrong and in the exact words without stuttering, mumbling, ect, say:
"My spell went wrong, Please reverse it, Don't mess it up, And don't pervert it."
