My father's mother passed away when he was 8 (of Leukemia) and it wasn't long afterward, she showed up at the foot of his bed one night. Seeing how he was the baby of the family, I think perhaps she was checking on him before she crossed over.

He said she was quite solid, with a bit of a glow - she never appeared to him again.
So, I think too, that it has more to do with their energy/emotional state (which, when you think about it, translates to energy!) vs. how long they've been dead. Hey - maybe this is why we don't ever see dinosaur ghosts - they only had an animal brain (Limbic), so there were no emotions attached, as there are with more complex brains in humans.
