Islamic Interpretation of Dreams (Ibn-i Sirin):
(Boring) Piercing a hole in a dream means deception. Piercing a hole in a stone in a dream means investigating someone in authority. Piercing a hole in the wall of a citadel in a dream means being obsessed with virgin girls and desiring to deflower them. Piercing in a dream also means spying, pursuing someoneâs tracks, desecrating oneâs earnings by bringing unlawful money into them, or it could mean deterioration in the conduct of oneâs children. Digging an underground tunnel in a city in a dream means searching for someone. Digging an underground tunnel to reach the inside of a house in a dream means trying to court a woman, exerting an irresistible influence on her, then luring her to deceive her.
