Thank you, mam, for your interpretation; I understand now. Here is another one.
I was with my ex at a river after walking in the current. I lost sight of her while I was going upstream to drop off a life jacket I wasn't wearing, and she was going downstream without a jacket.
There was another person I couldn't identify.
Strangely, there was a building in the middle of the river.
They told me she had been swept away by the current.
All of a sudden, there was no more water flowing.
They told me they had been looking for you.
In turn, I looked around everywhere without finding you.
I woke up feeling sad, with the impression that she had just drowned.
Looking forward to reading from you
