This is not true. I am sorry, but I have to say that you are being dishonest.
The Bible texts regarding spiritism (not all were included in my comments above) are very clear, unambiguous, unequivocal and explicit regarding the dangers of and penalties for engaging in spiritism.
For instance you interpret these events like being communication with the dead. But there's an interpretation this event is about communication with demons. And a lot more theological interpretations. These particular events say nothing to me.
BTW, where does your reason come from? Your immaterial soul or your brain?
Both if you mean reason as intellect.
But the ability to decide, the will, comes entirely from the soul.
