Hard Problem of Ghosts

If ghosts are the consciousness or energy of the deceased, what laws of physics do they obey? They are reported to pass through walls (insubstantial) but also make footsteps and move objects (substantial). They are visible to some but not others. This contradictory set of properties makes them impossible to model consistently. Are they psychic projections, interdimensional echoes, or simply stories? Any coherent theory of ghosts would require a radical rewrite of physics, yet the anecdotes persist.

Example: "The ghost was seen by three people but didn't show on thermal or EM. It could float but also slam a door. The hard problem of ghosts: constructing a single hypothesis that explains how an entity can be both massless and capable of kinetic energy, visible to organic eyes but invisible to sensors. It's like a bug report that breaks every known law of the universe's operating system."
