Dream About Saving Someone In Ocean

I had a dream twice. That i was near the sea and had to save someone, a stranger. I jumped in and swam thoward the drowning in the vast eerie ocean under a red sky. I got there rather fast and we were not far from the shore. But when i reached the helpless and took him on my back the retrieval was near hopeless. The shore was so so far away like the drift has pushed us deep into the open ocean. The water was still but when i tried to swim back to the shore, the land visible in front of me but so out of reach, i felt like i didn't move an inch. I swam and swam and swam, but didn't get close. The water was quite shallow for the deep sea but not enough to step on the ocean floor as it covered my airways when doing so. I carried the stranger, refusing to let them go. Even as i slowly started to realise that if helping him would be my dead i wasn't letting go of him. I swam and fought, and swam more and tried to keep him on back. Tried and tried to save him, to save us. And then just as i was feeling so hopeless I looked back. A huge wave high as a mountain was coming behind us. The tsunami hit us. The power of it made me feel so worthless before it. It was so huge and i was a miserable fleck that didn't stand a chance. It crashed and consumed us. As some miracle i survived it. But the stranger was nowhere to be seen. I was a bit closer to the shore but felt like a failure. I had to find the stranger. I couldn't leave without him. Everything was in vain. And so i swam once again toward the shore. And swam and swam. The swimming was easier but i felt the burden of my failed attempt. Because now this person was gone because of me. And i swam still looking for him.
