But that was the point. The dream came the most times to Faramir and only once to Boromir, and it was Faramir who should have gone, but Boromir came instead of him, obviously out of brotherly love and also the deep sense of duty he had, probably understanding at that point that such a dream was really of great importance:

It seems obvious that the recurring dream of this nature, obviously prophetic, seemed to be really important to the descendants of Númenoreans still, and especially in this time of crisis. If it was only a matter of asking about some totally random and unimportant thing, they could have sent some random bunch of soldiers and messengers, and not one of the Steward's sons...
