Dream About Living In Submarine During Holidays

My girlfriend, her daughter, and I were living in a submarine, and I think it was the holidays, because we hade an absurdly long dinner table with me sitting in the middle with the other two. Eventually the guests would ring a bell as if we weren’t submerged (it felt like we were but it was never addressed) we then, would open “the front door” aka the hatch, welcome them inside, make them comfy, then sit them at the table, the table was almost full when my hearing goes silent, I can see people are still engaging in dialogue but I can’t hear it, and then the lights start flashing red (only I noticed) and out of thin air my ex-fiancé appears in the seat across from me and just glares menacingly at me while deep breathing. No one stopped there conversations or even acknowledged anything odd happening, I was stuck in this silent stare down until I woke up.
