What are infecting dreams about?

So in my dream there was this stray cat that was infected with these worms that you couldn't see at first but they eventually grew to the size of tapeworms. At the end of the dream they were massive and slithering everywhere trying to enter me and my family members through any hole they could find. Any idea what this could mean?

I had a rather strange dream multiple times, I was saying that I was in a fairly small city, and there was a kind of disease, which affected humans and animals, for some reason, it affected my cat (this made them be very aggressive and even to kill), the only way to get rid of this disease was to shout at the infected and say all the bad things you think about them. On the side, I was in a hotel, and there was some kind of small fantastic animal, a mixture of a horse and a lizard, I can't quite remember what it looked like, I just remember the eye sockets, which had nothing on them. I couldn't understand him, since he didn't speak the same language as me, and I was curious about him. Shortly after that happened, I woke up, and out of a dream, I went back to sleep, and I dreamed exactly the same thing again, where I had left off. I started to ask about the blue bug, and they told me where it used to go, and I went to those places, but it was never there, but those who were in the place said it was.
Does anyone know what it means?

It was a fluffy pink and yellow thing with big eyes. It was in my kitchen on the counter behind the sink dancing and what not when I got my phone to record it. As I was doing that it jumped on me and burrowed under my skin. I could then feel it infecting my brain. Upon realizing what it was doing I fought back but I just ended up waking myself up. It was like I literally had to claw my way out of my own dream. Freaky as fuck.

So basically in my dream some edgy 12 year old jumped into a grizzly bear enclosure at a zoo and then "Orbus the grizzly bear"(?) who lived there approached the kid but then the bear got shot by the zookeeper so a group of internet trolls and memers started worshipping the dead grizzly bear which turned the entire internet upside down. A few years later,some super rich millionaire guy called "Jeremy Morstein" went to jail because the cops found out he was secretly smuggling drugs and shit but then he dies in his jail cell. After that a bunch of boomers wearing tinfoil hats went on 4chan on their laptops and found a guy named "Z" talking about how "drug traffickers run the world and they wanna kill donald trump" so they all start worshipping this Z guy like a cult. Then a bunch of trolls (the same ones that worshipped Orbus the grizzly bear) found out about a place called Region 78,and they started believing in some sort of conspiracy theory that said the U.S. government was secretly hiding living dinosaurs in Region 78,so the memers and trolls stormed it while wearing weird wacky costumes and shouting curse words because they "wanted to see dem dinosaurs". A few months later,a deadly bacteria named GLABAC-15 infects 5% of the global population and the epidemic indirectly causes a 3 month long shampoo shortage in supermarkets

I had a dream where there was an incurable disease that had infected the majority of mankind and scientists convince the world that drinking water is the cure, and this somehow cures everyone in the world because of the placebo effect but it doesn't cure me since some asshole scientist (played by one of my childhood friends) told me that the cure is actually a placebo effect. I spend the rest of the dream trying to convince people that the cure doesn't exist but no one believes me and I get chased and stabbed and wake up.
