Breathing trouble can be distressing for family members, but often it isn't painful and can be managed. Pain can be treated, too. But your loved one may have a hard time taking medicine by mouth. Hallucinations and visions, especially of long-gone loved ones, can be comforting. If seeing and talking to someone who isn't there makes the person who's dying happier, you don't need to try to convince them that they aren't real. It may upset them and make them argue and fight with you.
