Weired dream abd rats and fish?

seeing my fish tanks full of rats maybe 6-7- of them and first they were all fine living together there and then iam guessing rats got hungry( no idea how they breathed under water seemd like normal rats) they started attacking my cat fish and tear it apart, i tried pull rats out of fish tank and managed to do few of them out and then saw that my cat fish still alive but it was so pale and very transparrent, , but still alive- then all water cleared out and i saw 5 new fish in fish tank that i dont remeebr them there before they were clean fat and healthy and for some reason i thoguht it might be eggs of other fish that were buried in fish tank bottom for sometime and cause water was s muddy when fish and rats were fighting i never could see those new fish before- that is it - would to know what it means
