The facts and the explanation are two different things. I don't deny that people see things/ hear things/ experience things. However, the human mind is great at "interpreting" odd occurrences in particluar ways.
eg, I have tinnitus, and sometimes it sounds as if there's a jet engine warming up a mile or so away. Sometimes it's like faint bells. But I'm quite happy that whaterver the sound, it's a construct my brain's making to "explain" some unusual "signals" coming from the site of some damage to my left inner ear.
People with Charles Bonnet syndrome see all sorts of things that aren't there at all, and rather than postulate the spirits of dead people as the explanation of something odd seen, it would seem that a simpler explanation is that the brain "reaction" that causes people with CBS to construct complex visual hallucinations is part of a continuum of brain activity which can include occasional visual "misinterpretations" of stimuli in people who don't have CBS.
The chandelier in our sitting room had goose-neck arms, one of which used to move around from the vertical to the horizontal over a period of a day or so. Really spooky. However, when my daughter (bedroom above) was away for a few days, the chandelier didn't displace. Two explanations immediately came to mind: (1) although nothing obvious could be heard/ felt, my daughter moving around in her room caused sufficient vibrations to set the gooseneck lampholder moving. (2) the ghost or poltergeist that moved the lampholder became inactive when my daughter wasn't there. My reaction was that (1) was a simpler (occam's razor) explanation of the phenomenon than (2) so until further evidence presented itself, I considered the "mystery" solved. Other pheomena may not be as clear-cut as that, but somewhere along the line, it's likely that a rational explanation probably exists. After all, I've heard several people say that Derren Brown must *really* be able to read minds, as, otherwise, what he does is *completely unexplainable*. People are unwilling to accept that there may be explanations they just haven't thought of.
Extraordinary claims require extraordinary evidence. Rational explanations for phemomena may not be obvious, but that doesn't mean they're "unexplainable"...it merely means that you (or I) don't have enough information to make a rational explanation (yet?). To jump from that to "therefore it's the spirit of a dead person" is, IMO, a ludicrous leap of faith to make.
