Islamic Interpretation of Dreams (Ibn-i Sirin):

In a dream, repentance means release from prison.

It also means reversing the course of one’s life to attain success and to replace failure.

If one sees himself refraining from evil and sins in a dream, it means that he will be tried with an adversity, then repents to regain honor after humiliation.

If one repents for a sin he is not even aware of in a dream, it may be feared that he will fall into its trap, though the conclusion will turn positive.

If a musician or an adulterer repents from sin in a dream, it means that he may experience poverty after richness.
