The Hebrew verb chalam (חָלַם) means primarily "to dream" and secondarily "to be restored to health" or "to be made strong." The two meanings may be related through the imagery of sleep as the context for both dreams and physical renewal. Chalam appears extensively in Genesis in the narratives of Joseph and Pharaoh's officials, where dreams become vehicles of divine revelation.
In biblical theology, chalam represents one of God's primary modes of communication with humanity. Dreams in Scripture are not merely psychological events but can be divine visitations — God speaking into the unconscious mind of those He chooses to reveal Himself to. Joel 2:28 (quoted in Acts 2:17) promises that in the last days, "your old men shall dream dreams" — a sign of the Spirit's outpouring. The Joseph narrative shows that God's purposes cannot be thwarted: even enemies' dreams serve the divine plan. Interpretation of dreams requires the Spirit of God (Genesis 41:38), not merely human wisdom.
