They definitely could in D&D lore. You die. Your soul goes to whatever plane of existence. Your body gets left behind and a necromancer raises it as a zombie for menial labor. Your soul comes back as a ghost to complain to a party of adventurers about how a necromancer has defiled your body and you wish to put an end to it. The bard says something stupid like “well it doesn’t sound like you were using it anymore. You know what they say: one man’s trash is another man’s treasure.”
