The fish dreams🙄

So my bf's grandma dreamed abt fish recently not sure if anyone knows the story abt "fishdreams" . She dreamed abt them this time last year & my BF cousin had a baby  in February . They're family isn't very large & they're saying its 1 of 3 girls in the intermediate family .
 Does anyone know or heard exactly what the whole fish dream tells you ? Could I be a possibility ?
