Dream About Partner Falling In Canal

Last night I had a bad nightmare about my partner falling down a canal. It was very deep water with a strong under current with lots of weeds. I tried to pull him up but he sank further into the deep water. I was really upset as the current carried him off. I was stood there for what felt like a long time waiting to see if he came back up. Suddenly there was a hand on my shoulder and it was my partner dress in clean clothes wondering what i was staring at. Very weird dream.
