I realize this may not be the show to be a skeptic on, but do we KNOW that any of the dead people sightings are actually the souls of the dead people? We know that Hurley's imaginary friend Dave never existed. I believe Locke's vision of Boone was not a ghost. Kate's horse wasn't from the island (unless it was a different horse that looked the same). Yemi and Horace were dreams. Christian seems somewhat out-of-character.
We've seen lots of people die on Lost, and they are buried and decompose like anybody else. We know what death is.
The Losties have all been through traumatic experiences, day after day, for a prolonged period. None of us know what Dharma "experiments" may be wafting through the air. It may be more likely that "the island" (or, rather, some entity inhabiting the island) is pulling memories from their heads and projecting them (see Solaris), or that they are plain old crazy.
There are so many cons and deceptions on Lost that I don't take anything at face value. I will accept anything that is spelled out concretely, but until there is no other explanation, I'm not convinced.
I also believe that these questions may not be answered, so that we can continue to have these debates, even after it is over (see The Turn of the Screw).
