My father passed away last year. One item he always said he wanted me to have was a shotgun which had originally belonged to his grandfather. For years he had this shotgun stashed in the attic. After he passed, I had gone in the attic to look for it, only to find that it wasn't there.
A few months later, I had a dream in which I was talking to him and I asked him where he had put the shotgun. He told me it was in the closet of a spare bedroom. I called my mother and had her check, and sure enough that's where it was.
Now it's completely possible that my father had told me that when he was alive, and the dream was little more than a memory, but I certainly don't recall that being the case.
