What dreams predict is related to personal experience. Let me give you a general explanation: unmarried men and women dream of catching fish, suggesting that the dreamer will meet the right person soon, and need to grasp the pursuit of love by himself, and then the future will be happy. The second explanation, "the fish is big", can also show that the opportunity is rare, but we must grasp it well, otherwise we will miss it. The opportunity has come, and only those who have the ability can really grasp it!
