more weird fish dreams

In the past I used to dream a lot about fish for some reason. It's been a long long time since I've dreamed about fish, until last night. In this dream we were at mom's house, but she lived on a lake in a beautiful lake home on a very wooded and shady lot. That's pretty much the scene. There was a dock in the water and Dan kept going out onto the dock and checking this stringer he had hanging in the water. It was getting on toward evening and Dan all of a sudden realized he hadn't checked his stringer in a long time. It was beginning to rain and he made a mad dash onto the dock to pull up the string. I ran with him to find out what was up. He pulled it up and there were several fish hanging off it, some recognisable species and others kind of ugly unrecognisable ones. Dan seemed upset with himself for having these fish on his line. I thought it was kind of cool and suggested we could eat the fish for dinner. He said no, and I didn't know why not. Mom took the stringer and walked toward the house, I guess with the intention of cleaning them up and frying them. I was puzzed the whole dream what exactly he was doing dangling a fish stringer in the water. Then when he pulled up fish and got upset it was even more puzzling. I saw him take a big water bottle and start pouring the water all over himself, getting himself all wet, like he wanted to rinse something disgusting off his body. The water was yellow and brown and not at all clean, so that too seemed pointless to me. This is pretty much all I remember. When I woke up I seem to remember feeling a little sad or depressed, also puzzled because it had been such a weird dream. I did not wake up feeling refreshed, even though I'd had enough hours of sleep. The quality of sleep just hadn't been good.
