The subconscious mind sometimes filters unpleasant thoughts or memories that the unconscious mind wants to get out. Denial is one way this process may work. As a defense mechanism, denial enables a person to avoid confrontation with a personal problem or with reality itself by denying its existence. Unfortunately, dreams often subvert this process and can force a person to accept that a problem really exists.
When the northern kingdom of Israel was taken into captivity in 722 B.C., Judah did not expect to go with them. Because the people of Judah were engaged in religious activities, they thought they would be excused from God’s punishment. In particular, Jerusalem was thought to be a safe haven because the temple of God was there. Priests and false prophets told the people they had nothing to fear because their sacrifices guaranteed God’s protection.
Isaiah used the name Ariel instead of Jerusalem in order to trigger the people’s awareness of danger when he declared, “Woe to Ariel, to Ariel, the city where David dwelt! Add ye year to year; let them kill sacrifices. Yet I will distress Ariel, and there shall be heaviness and sorrow: and it shall be to me as Ariel” (Isaiah 29:1-2). The people’s sacrificial system had become a defense mechanism against their awareness that the Assyrian army was closing in and was about to attack Jerusalem.
Isaiah used the illustration of the subconscious mind at work during sleep in order to convince the people they were in denial about their future. He said, “And the multitude of all the nations that fight against Ariel, even all that fight against her and her munition, and that distress her shall be as a dream of a night vision. It shall even be as a hungry man dreameth, and behold, he eateth; but he awaketh, and his soul is empty” (Isaiah 29:7).
The problem the people needed to acknowledge was they had become spiritually numb and were no longer communicating with God. Although God had been speaking to them, they didn’t hear what he was really saying. They were tuning him out. Isaiah declared:
And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned saying, Read this, I pray thee: and he saith, I cannot; for it is sealed…Wherefore the Lord said, forasmuch as this people draw near to me with their mouth, and with their lips do honour me, but have removed their heart far from me…Therefore, behold, I will proceed to do a marvelous work amongst this people. (Isaiah 29:11, 13-14)
