My husband jokes with me not to bring back anything haunted.
I do believe things can hold onto energy. There are some objects I've literally been drawn to. But there are antiques that, upon picking them up, I wouldn't take home if the shop owners paid me. Are they haunted? Maybe. One time, I picked up a large metal urn that immediately made me feel depressed and sad. When I asked the shop owner about it, she told me it was an old burial urn. I have no idea why it was for sale, nor do I know if somebody's ashes were still in it! But suffice to say, the urn would not be coming home with me that day.
Just for fun, I decided to do a search on eBay for "haunted antiques." As of today, there are 141 items that show up in that search. Whether or not these items are truly haunted or sellers trying to cash in on the current fascination of "all things haunted" is unknown. But it makes for interesting reading.
