An older friend of mine who is very down to earth, doesn't believe in ghosts or anything that isn't real, told me about a hypnotist friend he had. They both worked at a radio station yrs ago in Birmingham AL. He said the hypnotist would come in and do a show on the radio. One time he hypnotized the receptionist and told her that there had been a large snowstorm the night before and the window had been left open and there were huge drifts of snow in the room. Then he asked her to close the window. When she got up she walked as if she was walking in huge snowdrifts. He helped a lot of them to quit smoking but it took a lot more then just one session to get it done.
He also used to do shows. He would ask a female audience member to come on stage. After hypnotizing her he would have her do things to show the audience that she was following his directions. Then he would tell her to strip. The audience would be like, "OMG she's going to strip." But the woman wouldn't strip. And that's how he'd show the audience that a hypnotist can't make you do anything you don't want to do. It backfired on him one night when the woman actually started to strip. After telling her to stop he found out that she was actually a stripper! LOL!
So all that to say, yes I think you should go see a hypnotist. Good luck finding your item!
