Yes, Ricky, you’re right. We are forbidden to have anything to do with spirits or ghosts, as they are often demons in disguise.
Maybe you could give your friend some holy water (you can usually find it in a church), and sprinkle it in each room. We asked our priest to bless our house.
Of course, if you’re talking about technology, anything’s possible. Phones and computers will develop glitches from any number of causes, none of which I ever thought were spiritual. Although maybe they are crosses sent by God to strengthen us and give us patience!
Here’s a quote:
The Bible provides examples showing the folly and failures of those who claimed the ability to predict the future based on their own powers or those of spirits (Daniel 2:27, etc.). God calls the word of diviners “nonsense,” “lies” and “deception” for foolish people (Ezekiel 13:8; Jeremiah 14:14; Isaiah 44:25). God said, “Woe to the foolish prophets who follow their own spirit and have seen nothing!” (Ezekiel 13:3). If an Israelite lived the deceitful practice of being a medium, it was punishable by death (Leviticus 20:27). The presence of a medium or spiritist among God’s people of Israel was considered a defilement (Leviticus 19:31). All these practices take people further from their Creator, the true and living God.
