Islamic Interpretation
If one acts irrationally in a dream, it means that they will act with disgrace, stupidity, or shamelessness in real life. Being irrational in a dream and intentionally using violent or insulting words, and acting deliberately in an evil way, means despair of God's mercy. It also means refuting or opposing something. It is also interpreted to mean attending one's prayers without the ritual ablution. Irrationality in a dream also may mean insolent behaviour, or ill speaking of people's honour or chastity.
