Islamic Interpretation
Reins appearing in a dream symbolize command over one's profession, authority in trade, or they may denote influence and robust financial health. They further represent a loyal servant or driver who follows orders without question. Mounting a workhorse fitted with such gear signifies holding a high office and requiring oaths of allegiance from subordinates. Plain, unadorned bridles point to a person of humility whose inner worth surpasses their outward appearance. Reins also signify security and restraint, like a safety belt. Donning a harness denotes safety and minding one's own affairs, though for someone facing trial, it suggests their evidence will be rejected, leading to defeat. Should a horse's reins break, it may herald the rider's demise. They further represent purity, guardianship, and safeguarding one's wealth, akin to the alms tax that purifies it. If the reins slip from one's grasp, it indicates religious decline, diminished devotion, or an unlawful marital situation. To see oneself bridled signifies abstaining from sin or keeping a voluntary fast. A broken bridle bodes well for its caretaker but ill for its owner. (Also see Bridle)
