The Hajj
Scholars have said that seeing oneself going to Hajj in a dream may carry multiple interpretations. If the dreamer is ill, the vision might indicate their passing. If not ill, it could signify approaching a ruler or a scholar for a need, beginning to repay a debt if indebted, or returning to prayer if they had abandoned it.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
Note: These are traditional scholarly interpretations (ijtihad) drawn from a specific classical source — not a binding religious ruling, fortune-telling, or a prediction of the future.
