What are parasite in body dreams about?

I dreamed that there was an aquarium in my brother's room with a number of fish and reptiles. During a few scenes, the water gradually diminished, but there was still water, and the fish were alive.
I started pouring water into it, hurriedly poured water until come across a creature like a worm, I said no, there is a parasite, went to the internet to search about it, it grew constantly until it was about 20 cm, came from there, went in the kitchen, its head and face formed Suddenly I saw a cockatoo kid that I love very much sitting on my left arm; and In the other hand, a Cockatiel sat down, a very beautiful and white couple, I talked to them a little.

I know it might be ridiculous, but I have a weird feeling about my dream.

I had an interesting dream last night, I had maggots coming out of legs as I itched them and a worm came out of a tooth that was suddenly rotten.

The most I can remember about the dream is first being in the bathroom, the lighting was warm with a yellowish hue and I look in the mirror to see one of my teeth had suddenly become rotten while I brushed. I brush out what looks like dark grey inch worm. After that I pull out the tooth in pieces though my smile still remained the same.

After that I found myself on my bed, a blue cover under me and I'm itching my legs as I itched them and a worm are removed from dogs). The next day I itch my legs in a different room and there's nothing coming out. I go to check my bed still with the blue cover and see that all of the maggots are there and dead. I take the cover to get ready for laundry. I wake up after that.

So what would you say this is about?

I had a weird dream of pulling worms out of my legs and squeezing them out of my face like a bad black head, they were the pink earth worms but a bit on the darker side of pink. Any idea what this means?

I had a dream the other night, and I can remember the full context, but in one major part, I'd looked at my left arm and there was a bug (looked like a bee or something similar) that had burrowed into my arm and was poking its head out.
I'd tried to grab it and pull it out, but it ducked back inside the little hole it had made.

I was just wondering if this kind of thing had any sort of symbolism or anything.

(I also actually could feel it when I tried to squeeze it out, so I'm convinced I was probably pinching myself in my sleep.)

Warning! This can make your skin crawl! It was a few days ago when I had a really disturbing dream. I saw something moving and pulsating beneath the skin of my right arm. In my dream I'm able to see through the skin and muscles, the creature looked like a white caterpillar. I didn't feel anything at first, but the more I observe, the more I feel the sensation of how it moves. It made my heart skipped a beat and was already panicking, but I forced myself to calm down. To my horror, there are more of them inside my body tearing away my flesh, drinking blood, and defecating. I saw some of their eggs, and there's also something crawling in my internal organs. My condition is getting worse yet I'm unable to feel the pain. I feel so confused and shocked, I couldn't keep my composure any longer. Then I realized that I'm dreaming and the dream ended just like that. I wonder what could this possibly mean.
