What are the ghost?

I think ghosts are the departed souls of dead people,but i do think they can use electric energy to manifest into a full body apparition.I think some ghosts walk through walls because ofresidual energy.It's not necessarily the dead person still there,but it's the memory playing out over and over.

Moreover, I'd say a 'ghost' is a conceptual apparition . An idea that exists at the edge of our minds,
which can in some circumstances be projected into a visual context. They neither exist nor don't exist, that is why they are ghosts.

I think they are a spiritual energy trapped between worlds, that haven't been laid to rest. They are still roaming around because something isn't settled with their death or their past life, or maybe they want to protect a loved one.
