If one acts irrationally in a dream, it means that he 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 to one’s prayers without the ritual ablution.
Irrationality in a dream also may mean insolent behavior, or ill speaking ofpeoples, honor or chastity.
