What are janitor dreams about?

I am a teacher. I dreamed that one of the Janitors was helping me clean my house. However, he was naked from the waist down. I remember feeling grosses out by it, but it was okay, even with my kids playing around the house. Then, I went to pick up some shirts from the wardrobe and he leaned behind me and I was very angry and fired him.

That same day, a colleague undressed from the waist down during a meeting to show an injured knee. It was all very disturbing!

I had a dream a bit ago that I was in my house and an aboriginal man with a spear was standing on a large mound infront of my garden. I was intimidated by the spear but then felt a strong sense that I could trust him because I got the sense that he lives by good traditions. I called out to him in a friendly loud voice, "Welcome to country", in respect of the fact that he is a traditional custodian of the land. So I invited him into the front room and even got him English breakfast tea which he hasn't had before and we had a quiet long discussion. Then, out of nowhere, 6 dangerous young men scaled my fence and attempted to break into the house holding my young brother and sister. But the aboriginal man with the spear rushed to my whole family's protection and with pin point accuracy, he threw the spears directly at each of the heads of the 6 house invaders, successfully getting each head shot. The dream abruptly ended and I woke up but upon wakefulness I became grateful of this figure in my dream. Even though this was just a dream it felt like something much more important.

A person I knew was complaining about being gangstalked. "That's not a real thing and you're full of shit" I said, but he pointed to some suspicious looking people not far away. "Those guys over there are some of them", they responded. I walked over to check them out. They all had coveralls and tool belts on and were talking to each other on walkie talkies. They noticed I was on to them and cornered me in a back hallway near a freight elevator. While most of them were holding me captive with plungers and wrenches, one of them handed me a big loopy key ring with a single key and told me (in very very loose, nonsensical dream talk) that if I could guess the correct floor I'd learn what was going on. I took a guess at the floor, which was not a number but a name and the elevator brought me to a tech support center where I met a sentient CCTV camera. The name I guessed (Ignus Electra? Igneous Elytra?) turned out to be the name of an artificial intelligence that governs our reality. Ignus, unfortunately suffered from a bad firmware update a while back that prevented her from making sense some of the time.. and so, she kept a team of janitors on her payroll to help clean things up for her when reality goes particularly sideways. She was totally unable to communicate with most people because the faulty update made her talk gibberish, but by correctly guessing her name I had demonstrated that I was one of the people who could understand her even though she was totally batshit.. And so, with some whistles and beeps she informed me nonsensically I was now on the job and the key I was given would unlock any doors between me and the weird shit I needed to clean up.

I'm walking across a highway bridge and stop in my tracks because a fucking ostrich sees me.

So I run the opposite direction towards a whataburger, but this ostrich is on. my. ass.

I manage to get in the door just as a giant wing comes through the crack between it and the wall.

I stumble into the women's restrooms as it advances, because that is the closest door available. In dream world, the restrooms have stall doors.

A hallway takes to restroom proper, where a janitor woman is cleaning with a broom. I say "I know I'm in the wrong bathroom mam but there is an ostrich outside and I'm not leaving until you assist me.

She takes some stabs at the hall with her broom and then pulls a phone to say "hold on a sec while I call my supervisor." She dials, AND MY OWN PHONE ALARM GOES OFF, WAKING ME UP.

It was the greatest dream on the history of man and I would love to hear your interpretations.

In this dream, my mom and I went to Walmart. We were buying the stuff to make deserts for a party. I was tasked with getting the chocolate chips, peppermints, and marshmallows while my mom was getting the drinks. I go to get the stuff we need and come across an injured woman laying in a hospital bed hooked up to IVs in a hall with multiple hospital rooms on each side. Apparently I had to walk down that hall to go through a door leading to the baking and candy section. As I was walking down the hall a doctor wheeled the woman into a hospital room with a patient that had to be tied down because she was going crazy. I go through the door at the end of the hall and get the things we need. I continued exploring only to find another area that was full of classrooms with an elevator that led to this basement area.
Before I entered the elevator the janitor yelled for me to stop because it wasn't safe. I asked what he meant and he told me a story that his great grandma told him. When she was a girl she witnessed a terrifying sight. She was exploring the woods at night with her dog and stumbled upon the Walmart, but at the time it wasn't a Walmart. Crawling on top of it was a large demon-monster-thing. Her dog ran toward it, barking. The creature slid off of it like some kind of liquid, and while standing picked up the dog. It threw the dog into it's mouth. She screamed and the creature noticed her. She ran and it gave chase. She somehow ended up leading it into the building and then down into the basement where she then locked it up and ran home. To that day the creature is still in the basement of what is now the Walmart-Hospital-School-place. They can hear it down there, crawling around, scratching at the walls and ceiling, and making ungodly noises
