Dream About Giant Worm Creature On Road Trip

Parts of this dream I don't remember. But, I was on a road trip and had to make a stop. When I did, I discovered a thick worm like creature that had a mouth on one end with sharp teeth. In the dream, it felt familiar like I had seen it before. I watched it move through various cycles of its growth until it was large enough to consume a human. I left and found a friend to bring back with me to help either kill it or neutralize it. When we came back, the giant creature wasn't there, but a small one was just beginning its life cycle. I demonstrated to my friend how it latches on to a living creature by letting it latch onto my fingernail and we watches it root around trying to find skin. It managed to bite me longer enough to give it energy to start eating itself and shed its smaller skin to grow into larger skin. At the larger size, I became more conscious in the dream and told myself to use salt or sodium dioxide to neutralize it, so my friend went to find some. A nearby cat became curious about the worm in its newer larger body and started trying to rub against it affectionatly. Out of concern for the cat, I tried getting it to move away from the worm, and that's when I woke up from the dream. Editing to come back because I remembered another part of this dream! Before the road trip and worm, I dreamt my husband and I had received word that his mother had passed away. He's not close with her and hardly ever talks to her, so we weren't notified until a post was made on social media about her passing. I remember in the dream that I was going back and looking at her messages to me and wondering what had happened to her because she had just engaged with me a few days prior and no one seemed to know what caused her death.
