Screaming or howling

Me and my sister are in a submarine with and older man with grey hair and his son who looks older than me and my sister. The submarine malfunctions and the man says he has to park it on the sea floor. He does not have time to find flat sea floor to park it because it is already going down so it is gets parked on a hill underwater making us a little tilted. The man then tries to use the submarines phone, but it does not work either. The man says we have to leave the submarine than try to swim to the top. The older man and his son go first, they go behind a door then close it and me and my sister do not know what happened next and we worry that we will not know how to get out. Then me and my sister walk towards the door but then we feel the submarine falling to the side it was leaning and me and my sister slam into what was the ceiling and we panic because now the only exit is beneath us trapped shut by the sea floor. We try to figure something out but there is nothing to be done, so I go and try the phone again, first try it was static. Then the second try I got the phone to work so I hurriedly called my grandma thinking the phone might go out again. She picks up and I scream into the phone that the submarine went down on its side and on top its only exit and that we will not make it long because the monitor in the sub says that it is losing oxygen pretty fast. <PERSON> sounded like she was trying to be calm at first but and survey the situation but then she started to sound worried and got quiet, and then sounded like on the verge of tears and asked if there was anything I wanted her to know, and I knew we all knew we would not make it so I started to weep while telling my <PERSON> that I love her and that she is the only reason my childhood was good and said some other things and then I gave the phone to my sister so she could talk. While they talked I looked around the sub for maybe an exit I did not see before but then I woke up.
