I had been having a dream where I saw thousands of goldfish in a river beside me, but one had fallen out and was about to die. I rushed over to help it, and rapidly threw it in the water with the others. A sudden feel of relief and happiness came over me.
After I woke up, I searched for the meaning and stumbled across a feng shui belief about goldfish and good luck. There are supposed to be 9 in total, 8 gold and 1 black, the black fish is supposed to neutralize bad luck.
