Dream interpretations please?

this was currently last night and here is my dream. I am on a shallow beach/pool in Las Vegas with my mother and my brother and we start swimming going to the right and as we are ping all of these hotels that are on the vegas strip i look under water and i see a man made steep drop and inside there are alligators and there are some around and as soon as they see us they jump in the water like they do when hunting. This "drop" looks like a pool in it. For some reason we jump in. The pool just reaches above my moms and she is 5'9 but i still can stand up straight. I look under water again and there is nothing by my brother and i see that there is an alligator right between my mothers feet so i panic and swim up and this is exactly what i say, "MOM! There is alligator right by your FE-!!" and then an alligator takes me right by the shirt above the shoulder (i am wearing a shirt over my swimsuit, im self conscious so i always do this) and starts dragging me to the side and i scream my moms name and i wake up screaming with my mom almost shaking me to wake up! Can someone please tell me what this means!?!?!?!?!?
