Source: The Great Interpretation of Dreams (Ibn Sirin)
(By analogy with a road and alley) A corridor in a dream indicates a transitional phase or a narrow path. If it is wide and bright, it is relief. If it is narrow and dark, it is worry and hardship.
Source: Perfuming Humanity in the Expression of Dreams (Al-Nabulsi)
(By analogy) A corridor indicates striving for a matter. Its end indicates the end of that matter.

(By analogy) A narrow corridor is interpreted as worry, and a wide one as relief.
