Vintage silver cross HNTD

I bought this necklace from a lady who contacted me bc I collect haunted items, she said this necklace came from an old church that was turned into a home in Massachusetts. She said she has seen the figure of a woman crying walking in her house, sometimes hearing the crying w/o seeing the apparition. I have had it for 3 years now and have also seen this woman. I have had doors open by themselves and my pets will not go into the room I have this hanging. A medium told me this cross has Native American heritage and was cursed when it was stolen from the original owner long ago. I obv can’t guarantee that you will have these same experiences if any but I know what I’ve personally experienced and had other people independently take this item w/o telling them anything. They all brought it back to me within a week. I believe it’s sterling. Not sure about the chain
