LivingbyFaith,
A missionary once told a friend of mine that the darkest place in the world (for mission workers) can be found on a Native American reservation in southwestern South Dakota. I have to wonder if the darkness and strongholds linger as they do because much of the sorcery is overlooked as harmless and/or valuable, art and culture.
i.e. I saw a pair of dream catchers go for a LOT of money at a recent fundraising event. Raised more money than anything else donated for the sale.
So while on the one hand -- I wouldn't necessarily fear going into a home with a dream catcher per Romans 14, I also would not want one in my home because they are well known to be linked with contacting the spirit world (sorcery, necromancy, etc). I also believe I would have to counsel a Christian who owns such things, as you did. Per Acts 19:19: A number who had practiced sorcery brought their scrolls together and burned them publicly. When they calculated the value of the scrolls, the total came to fifty thousand drachmas.
