Submarine dream

Date: 11/17/2018

This dream takes place in a weird underground water park type thing. I boarded on this submarine thing with me as the driver and a passenger beside me. We exited the underground water park into the deep ocean where we were driving and I kept hearing sonar beeps. (Look up sonar sound if you don’t know what it is) then the passenger suddenly pulled me out of my seat and started driving the submarine not knowing what to do and eventually crashing into an iceberg. I remember not being able to breathe for like five seconds. Then a creepy part happened. I heard the SOS distress signal in Morse code (look it up) then seeing my dead body looking like it had been stabbed but floating to the surface of the cold ocean. Then the SOS was so loud I felt like dying. but then waking up.
