Their spirits come and visit their loved ones I believe ...
My dad had a very dear friend that came to him a few days after he died and told him how to take care of some unfinished business my dad didn't even know about. He was skeptical, but went ahead and did what his friend asked him to do, and at the end, it turned out that were things very important and needed!!

Keep your ears and eyes open, maybe Neal needs you.
