Waking up in the Future

well if i were to wake up in the future i would imagine it to be underwater.. like that one Jonas Brothers song. but everything would be so high-tech. like idek dude. everyone would have there submarine cars and stuff just driving around and all i  can imagine is a big cafe where you can pick anything you wanted to eat and  a laser would just whip it right up in front of you. like faster then fast food. all land animals would have adapted to the water and they would all have fins. but they wouldnt exactly be like fish. cats would still have there fur.
