What does it mean when you dream that you are swimming in crocodile infested water?

last night i had a dream where i saw a mive truck collapse onto a building and it crumbled into the water then a domino effect happened and the buildings next to it, one of which was novotel hotel also crumbled into the water.then in the same dream i find myself with my family having a coffee at hotel intercontinental, then walking with my mum in murky crocodile infested water. a crocodile wanted to bite me but then i stood very still and it ped me. i grab on to a ledge and try to grab my mums hand. in the end i didnt grab it and the dream ended.
