Being Sold as a Slave
Scholars have said that whoever sees themselves being sold as a slave in a dream, Allah may constrict their affairs and humiliate them. As for someone who lends or borrows something, they might gain a temporary benefit, or they might gain it if the item is desirable.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
