What are crime dreams about?

So today I slept for like 4 hours in a flight from Shanghai to Amsterdam and I had a dream where a friend of mine suddenly had the ability to read other people's minds and check if they were lying... by putting his hands into their pants...

In the dream he was widely known for this abillity and was repeatedly hired by law enforcement to solve crimes. Further out in the dream he bragged about it in front of me and his other friends.

I joked and said: as long as you don't put your hands in my pants lol. The problem? I said it out loud...

So everyone from flight MU771 today who was speaking dutch and heard it, sorry!

I was a clerk or trainee lawyer at a law firm. There was candle wax dripping on the floor. Very scholarly place. Maybe there was a globe. I was taken through a secret passage under a mat beneath the table and my legs were really achy and tired and I was told my three women that there was a problem no one was admitting to in the world. It involved the fact that people could not die anymore. A cure all medicine had been discovered and people were taking it and just not getting ill or killing each other perfect. No hate in the world. Perfect. But not so perfect was the fact that a side effect of the medicine was that each night you fell into a deep sleep and your skeleton came away from your body almost completely bloodlessly and was really brought to life. With a life of their own skeletons wreaked havoc some were good and some were bad some stole and set suburban houses on fire some were involved in government corruption and violent crimes. People woke up maybe feeling slightly achy but ok though they woke to disaster. The skeletons were drawn back each night to the warmth of humans and something that got repeated a lot was that they felt the cold. But of course the problem was if you arrest a skeleton then you have to arrest the human too. I mean too long apart could disable or kill a person and make their life difficult like obviously no walking or standing up without prompts. So what do you do when a criminal occupies the same space and body as an innocent? The three elders said they were off to make lunch in a grandfather clock and were quite mocking about how tasty lettuce and tomato and mayonnaise was (no bacon though, pork was banned) and how I could have none of it. It was prohibited and reaching some kind of alternative dispute resolution with the skeletons was now on my watch. Then they waved a fob watch like a hypnotist in my face and waved their hands and said “ooh!” They left me with a broom and a soggy paper brown bag for lunch which had two bones of a rib cage in. I found that really insulting and I said shut up what you have done here is degrading so I will leave after all. I tripped up on the door and it was quite embracing.

I felt guilty about my own prejudice because I probably said I hate darn skeletons they’re all tricks and liars...

I dreamt that I was me (f27) and that I was a serial killer that murdered people of a similar age for me.
It was usually in a very bloody fashion; spurts of blood would fly out and cover the walls but the method was different each time.

For example, during one murder in a Chinese restaurant, I turned into a tiger and attacked three victims subsequently killing them. This was the only murder I could remember clearly.

The weirdest part was when the police were closing in on me. They seemed to be so close to capturing me but my biggest (and only) worry was not being able to turn in my art project as a fine art student. This was because I had been painting my crime scenes (before the murders) in a large sketchbook. They were extremely detailed and beautiful paintings and I was so annoyed that handing in this amazing portfolio of urban landscapes might get me arrested. I wasn’t worried, I was annoyed! Me in the dream was so nonchalant and casual about my crime. I was so irritated by everyone and the fact I may have to redo my art, particularly the painting of the Chinese restaurant. I had painted the paintings on the walls so it kind of felt like painting inception.

I decided to hand the portfolio in anyway as I thought to myself, I would rather not waste my time creating another one. Jail would be better. That was when I woke up and was me again.

For background: I'm a 22yr old woman, I'm single, I've no children, and I live with my mom and our 2 dogs (I'm obsessed with true horror stories though, which I'm sure spurred at least part of this nightmare)

The nightmare: I wake up in bed. I'm not sure what woke me. I turn to my husband. He's looking at me, confused. We hear bloodcurdling screaming. It's coming from our infant son's room. There's something wrong about this scream, it's not a normal food/diaper change scream. We jump out of bed. We're running down the hall. I reach the door first. I look in. I see our daughter, a toddler, in our son's crib. She's raping him. I gasp and start crying. I fall away from the door. My husband rushes in. He pulls her off of him. Our son dies from the physical trauma. The dream blurs and changes slightly. I'm now sitting on a chair. My husband is kneeling in front of me. Time has passed, but not much. Our daughter is nowhere to be seen. I look at my husband. I say "I don't know how I can face her..." referring to our daughter.

Then I wake up.

Please, for the love of all that is holy, I need help interpreting this, because I'm at an absolute loss. I know I need to take a break from watching true crime/horror stories on YouTube for awhile (I was/am fascinated by cold cases and serial killers and the like, but had already been stepping back from that content to give my mind a break, the most "violent" media ice consumed in the last week is Hollow Knight and The Rocky Horror Picture Show...)

I've honestly never been more relieved to wake up from a nightmare, though, I'll tell you that...

I’ve (26F) been watching true crime since a couple of months now and I admit maybe the dream was because of this..

Onto the dream. I was basically living in this American household where my dad and mom were divorced and my mom left me to take care of her two kids a son and a daughter. Both were away for business so I was looking after them.

I think at some point I got irritated by them and killed them. I didn’t see this part but I jumped to the part of cooking in the kitchen with meat which I knew was theirs.. I waited till the water boiled and carried out the cooking as if it was super normal. After making the curry I sat in the living room sobbing and scared about jail and my parents and why I did it. Like wtf.

Then dad came home and I thought oh so it was my dream and I didn’t kill my siblings.. but then he goes to the kitchen and uncovers a pot of curry and asks me about it saying it smells funny. I say it’s old and immediately throw it all away thinking I’m about to get caught.

I woke up screaming because it was so horrifying for me. I thought it was all real and was so confused and scared when I woke up that I killed someone..
I wonder if this dream means something or if it’s just a projection of all the true crime stuff I watch.
