Was what the questioner saw in the dream a punishment from God? And will repentance for his past actions benefit him, especially since the violation of honor occurred before he reached puberty?

Faith increases with obedience and decreases with disobedience. A Muslim must observe Allah's obligations and avoid His prohibitions. Disobedience deprives a servant of good, but Allah has opened the doors of repentance for those who err, and "the one who repents from sin is like one who has no sin." A Muslim must strive and rely on Allah, for repentance can change the course of life for the better, and persistent remembrance of Allah fortifies the soul against Satan.
