A Laughing Dead Person
Scholars have said that whoever sees a dead person laughing in a dream, this may indicate that their sins have been forgiven and they are among those granted forgiveness, citing the Quranic verse: "Some faces, that Day, will be radiant, laughing, rejoicing."
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
