The camera shoots ghosts

There are no ghosts in the real world, but there are ghosts in your mind. The camera can't shoot ghosts, but what looks like ghosts are all virtual shadows, just the false shadows of multiple beams of light refracted by the lens and recombined on the film. You can try it if you have time. Shooting them in dark places around many point light sources sometimes projects images of people around them.
