Has anyone ever come to you and claimed to have spoken with a deceased loved one?

This happened to my daughter recently, when someone she had met once or twice claimed to have been in contact with her deceased sister. Although some of the details fit, they were also rather general, except for one thing which was remarkably accurate and really had nothing to do with her sister but did have to do with me. I am highly skeptical of such claims, if not completely disbelieving, but wonder how others in this situation have reacted.
