Dream fragments from the week

I remember fragments from the last couple of nights dreams.

Recently I was dreaming of a river. There were times when the river traffic was very low and not many ships on the river. At other times it seemed as congested as Chicago at rush hour. In one of the congested moments I remember seeing a tall white boat with several decks. It was surging forward, almost as if it was passing other boat traffic, and then it tipped up on its front and sank almost immediately top first into the water. I remember looking at that scene thinking "oh my goodness there must be a lot of people on that boat/ship". I was thinking about them rushing to doors and trying to free themselves. I watched the boat for a long time. After a bit I thought that it was quite a lot of time and worried they wouldn't survive. I kept watching the water for survivors to pop out. Finally I saw a lot of bodies. I looked closely to see if they were swimming but none of them were. I realized they were all dead. I was sad.

Then a couple of days ago I only remember that in part of my dream there was a small pig, alive. He was cute. Then I remember seeing the pig and he was dead. He was all black and the back of him was split open. Large black spiders were crawling out of his body.
