Did any one know what is the meaning of catching fish in dreams?

i go to the Internet after i wake up, i search and search until i come to some sort of sites describing about my dreams, they said the maybe I'm pregnant or someone of friends and relative maybe pregnant and so i went out to ask my sister living with me. And guest what she is really delayed and really want to check with the doctor.
To make it short, its true!!!! pregnancy is really a joyful news.. why is pregnancy of sister got a lot of premonition, lots of our friends dream of her being pregnant and have a baby girl.
