Unknown Debt
Scholars have said that if someone sees themselves burdened by an unknown debt in a dream, this is interpreted as consequences of sins and transgressions that have surrounded them. It is said that they will be punished for these in this world through illnesses or certain worldly afflictions.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
