What are emerald dreams about?

I had a dream it was like an olden times and an old man got mad at a woman because she lost the ring he gave her so he made her promise to go to the bottom of the ocean and get it for him but in order to do that she had to cut her head off and somehow she was still alive with her head off and talking saying oh look at the ring I promise I'll get it for you because I love you or whatever. And the body was wearing this gorgeous emerald evening gown with fur around the neck but somehow her head had to be off her body and I realized he was just trying to scam her so she wouldn't be able to get out of the ocean and she hung over the water and he cleaved her head off her shoulders and does the water took her away he was like an electric man and somehow the water got shocked and the head turned black from electric shock and you just see her tongue hanging out as the head start screaming while being electrocuted

For context: kuchisake-onna (口裂け女) or “the cut-mouth woman” is a figure from Japanese folklore. She approaches people on the street at night, face obscured by a mask, and asks them, “Do you think I’m beautiful?” If they say no, she kills them. If they say yes, she cuts the sides of their mouths. She asks, “Do you still think I’m beautiful?” If they say no, she kills them, if they say yes, she makes the cuts wider until they match her own.

In this dream, I was in a museum going down a hallway of little dioramas inset in the walls that had recreations of different Japanese animals in their respective habitats. While I was turning a corner, a woman approached me holding a mask in front of her face. She had a red kimono with red-orange and white flowers, and these teal-y emerald green leaves. She had long, straight black hair that was almost to the ground. The mask was a blank white with a blush on the cheeks and painted lips and eyebrows.

She asked me, “Do you think I’m beautiful?”

I said, “Do you think you’re beautiful?”

She didn’t say anything for a minute. Then she said, “Yes,” but she sounded scared and kind of sad.

I said, “Then you’re beautiful.”

She didn’t say anything right away. Then she tucked her mask into her sleeve and looked at me, then held my hands very tenderly. She said, “You’re the first person to ask me what I thought about myself. Thank you.” She smiled very kindly. I smiled back and held her hands, and gave them a friendly and supportive squeeze.

She let go of my hands and then walked past me with a very gentle smile, standing up very proudly.

There was a little more dream, but that one felt very vivid and intense on its own. It felt good to be kind to her, even if it was just a dream. It felt good to be kind in general.

The dream started with me being on a large train station I had a whole bunch of stuff with me that I tried not to forget. I looked at the station and was Breda Central Station (Netherlands).

I stepped in a random train without thinking much while carrying all the stuff (it seemed like 2 backpacks). The train didn't move forward but instead got broken.

I heard through the intercom: "Our train got broken, but we will fix it by getting a new locomotive."
"Shall we sit down or take another train?" A random woman asks. She sat across me. She was overweight, had blond hair, earrings with an emerald gem in each of them. She wore a purple dress.

"Hmm, I don't know how long the repair will take", I said wondering myself if I should get off or not. I even began to worry where I was going, or that if I was in a hurry or not.

The conductor came inside my wagon and asked me: "Hey that bongo outside, do you want to take that with you?". He pointed out to the window and I looked outside. A pair of giant bongo's stood outside, it was a really weird sight. "I don't know what I have to do with that", I said with doubt as I grabbed my phone and started texting a Whatsapp Group that seemed to have something to do with the bongos. I didn't get a reply in time, and the train started riding away.

After what seemed to be a long time, I looked outside and saw lots of grass and other railroad tracks passing by. The ride took many hours in dream time. I could see the whole thing, it was beautiful, really relaxing.

The ride ended and I stepped out in another station. There was a young girl hiding behind some pillars in the station. She kept getting closer to me and I saw her expression, it looked really devilish.

I knew that it would turn in some kind of demonic nightmare so I just turned my back to her, and walked outside the station, thinking "If I don't see her, maybe she will disappear".

Once I walked outside, I stood in a garden, and around me were all kinds of wedding decorations... I was like... How did I suddenly get here? I got lucid at this point, I started deepening, feeling the grass.

I looked around me. Behind me was a house of Roman architecture (Like this building: https://www.timeout.com/rome/attractions/pantheon), which was the station I just walked out of (somehow it turned into that building).

I looked to the right, and there was a path that led up a hill, and from the sounds of it, there was a beach behind the hill.

On the right there stood 2 older women by a tap with lemonade in it, sitting on a small (equally white) table (Looks like this: https://i.pinimg.com/originals/cf/4c/40/cf4c40e8cced3710c501210492ec6b05.jpg).

Being lucid, I thought of something crazy. I grabbed the whole jar and opened the tap and just held it above my face and just drank straight from the tap. I had to laugh inside the dream cause it was something I wouldn't dare to do in real life!

Then, I thought of something crazier. I have a workshop tomorrow in real life, and I knew that in-dream, so I looked at one of the women and told her: "Hey, I'm giving a workshop about this world (referring to a lucid dream) tomorrow."

The woman straight up disappeared in my view! She just looked at me, and started fading out!
I then looked at the other woman and told her the same thing. She then replied: "Oh that's nice, I usually take a hot shower after a lucid dream but it got so expensive that I don't do that anymore.."

I woke up, feeling trippy as fuck that I managed to pull a reply out of this!

The beginning of this dream was weird. I was in a game with other people that involved Minecraft items ( iron nuggets, gold ingots, and emeralds ) That we’re in a box. We had to choose one item. If you didn’t choose an item you would get killed using a shotgun. This game was being played in an old, abandoned kitchen. The owners of the house was a weird guy and his girlfriend, I forgot what they both looked like. We each picked an item from the box when they told us to. When it was my turn to choose, there nothing for me to get, the box was empty. I panicked, and was told I was gonna get killed. Some people were happy that I was getting killed. I got kicked over and dragged into a room, which was just like my room, but with an old couch and a big TV. ( My room has 1 blue wall, and 4 white walls and a carpet. ) I was on the ground, scared about what happens after death. I started thinking this going to be a painful end, and that I was going to be killed slowly. I don’t believe in heaven or hell, I started thinking that death was just and endless, eternal void. I was also wondering what it was like getting shot by a shotgun. The guy then went to the bathroom to get his shotgun, I asked his girlfriend to help, but she didn’t. I asked her to knock me out with a tranquilizer dart, She said yes. When I got shot, it did nothing. It felt like a needle, but nothing was happening. Then, she went to the bathroom to help him with finding the gun. And then I noticed that they had a second gun on the wall, so I got up to get it. My plan was to shoot both of them so they couldn’t move. They were across the hallway, in the bathroom still looking for the gun. I tried to load the gun but then realized it was a fake gun. Then, they realized that all their guns were fake. They let me go but told me that they were going to kill me tomorrow.

I had this dream where I was dying to piss, so I go into my bathroom and when I do it, for some reason it was like a neon or emerald green. Then all of a sudden I realize I was on the verge of doing it in my sleep before I wake up and pull my sheets off and rush to the bathroom for real. This has never happened to me before and I worry it means something bad, or am I just overreacting?
