@Staaaa idk but there's an old myth told that if u woke up and suddenly have an unknown bruised on your body, that means the ghost bite you (it's a myth but yeah this is horror mystery and paranormal story anyway, no science involved) 😌 maybe something similar to that. Or maybe it's not really a dream but his sleep is actually a "gate" for another/ghost realm, which his soul can enter 🤷♀️
