Islamic Interpretation of Dreams (Ibn-i Sirin):

(Blame; Calumniation; Rebuke; Reprimand; Reproof) Ifone sees himself censured by a prophet, a saint, a godly person, or a bosom friend in a dream, it means repentance from sin, refraining from walking the avenues of error and temptation. Censure in a dream also signifies love and compassion.

If one rebukes himself in a dream, it means that he had indulged in a wrongdoing which he regrets and that he is blaming himself for it.
