Do the temporary ghosts of resurrection stone and “priori incantatem” count for you ?
That could only work if “permanent” ghosts are really made from souls (Dumbledore hypothesis), but the temporary ghosts are made from memories (HJPEV hypothesis). While it’s not impossible to have both mechanism, Occam’s razor gives it a low prior, I would more suspect the same mechanism behind both.
