What are fantastic being dreams about?

I saw my self morphing into a giant python in my dream in a big sea and woke up. When I was half awake I saw someone sitting beside me and asked who he is, he said he is Tannin. I've never heard that name before so I googled it and found out he's a sea monster serpentine monster

I'd like to start off by saying I'm not a religious person. I would never deny anyone their own beliefs but I myself find I don't need religion to help get through day to day life. I believe in the golden rule and the possibility of a higher power both good or evil but I don't have a specific religion I'd stake my faith in. That being said I had a dream last night that has me a bit curious.
In my dream was at my grandmother's house and lots of my family were there. Although I can't remember exactly who. They are all Christian though which is part of why this dream seemed so odd to me. Anyway, I was sitting on a couch talking to someone next to me, and somehow we end up talking about the Value of Death. I said something along the lines of "This thing (with which I don't recall) is worth the death of many people." And just after having said that I felt an intense static in my legs and then was totally paralyzed. I panicked a bit and told the people around me amd everyone got silent and just stared at me. Then I felt a very suddenly intense pain radiating from my neck throughout the rest of my body which just kept pulsating and never dulled. It caused me to scream but still everyone was silent. Then I felt something, as I'd there were someone leaning into my ear to whisper, but no one was there. And what I heard was quite frightening but I lack the proper words to describe it. Something far worse than impish nonsense but that's the best description I could give. And then nothing. I was telling everyone what was happening and one of my aunts, I'm not certain which one, said we should give Him a call. Then proceeded to take a phone to another room. When she came back a very handsome man, in dark clothing was behind her. He glanced down at me very briefly and then began to survey the room around him as I'd it were a bloody crime scene. For a moment I even saw it from his perspective and it was quite a mess. Then he told me his name was Lucifer and gave me a kind smile. Next he said "A evil of greed had bitten me." Staring at the wall by the TV as if he were looking through it he began to explain that my mention of the Value of Death, the devilwas nearby and listening. However when it realized there was nothing a "value" around me it threw a tantrum much like a child, which is why it had bitten me. But apparently it took off in a hurry. Lucifer then leaned down and placed a kiss on top of my head and the pain and paralysis disappeared instantaneously. He smiled kindly at me once more and told me that I would be alright and needn't worry. Then he was gone. As if he had never been there at all, everyone around me began moving and talking again. But all I could think about was how my aunt was able to get ahold of Lucifer himself via phone. Why she would have contact with him as she's very Christian and would never associate with The Devil so casually as if she needed his help? Then I began to wonder if something like this happened again how would I get ahold of him myself to help me. And when I woke up I was in a state of shock. Anyone have an ideas why I would dream of such a thing so randomly?

In this dream people kept referring to me as "Lucifer." As in the devil. But instead of seeing me as a devil, they saw me as their devil. It's as if a religion was formed around me. One day in the dream, I decided I want to travel. It's been a while since I traveled anywhere so I decided I wanted to visit the countryside. Two people came with me, again they still refer to me as Lucifer. At this point I got used to it, but I'm still mildly annoyed by it. We reach the country side, it was just fields and fields of wheat, the warmth of the sun was pleasant, and the cool breeze made the wheat dance. (not literally)

Then I saw this boy. He was short, had white hair, and he was wearing a cloak. He was crying on the side of the road. I didn't just want to leave a random crying person on the side of the road, so I approached them. And when he saw me, his face lit up and he asked "Are you Lucifer?" Seeing the fact that the title Lucifer being given to me made people happy, I decided that I'd embrace the title. I told the boy that I am indeed Lucifer. And he became so happy that he hugged me. I went back to my two followers along with the boy. We stayed and enjoyed the countryside. And the dream ended abruptly.

I was just wondering how this is possible due to the fact I’ve never had a lucid dream. If I see like a scary creature or anything that is a creature or if it’s living I can make the dream a sex dream. For example last night I had a dream that I woke up from a dream and there was a weird woman standing at my door and I felt terrified, it’s like my mind that was awake forced me to fo up to her and kiss her and ask her to have intercourse with me. Obviously this wouldn’t work in the real world due to obvious reasons, but I was wondering how this was possible if I’m not lucid dreaming? I haven’t had a real nightmare since I realized I could do this.

i had a dream where i was driving to my grandmother’s house & looked up at the sky to see Lucifer was in the sky and God was basically in hell. Lucifer’s horns were the shape of clouds but he was still in heaven and then God was on fire, so he was in hell (in my dream— i’m trying to be more specific about how it was). we all know it’s the other way around in real life and yet in my dream it was the opposite. and then as i was driving, God begins to chase our car and then he turns back around— he “turns his back on me” as i thought in the dream. i woke up from this dream at exactly 4:44AM. what could this possibly mean? i do believe in God. i pray to him all the time and he blesses me so i am quite confused, although as of lately i have been questioning Him but who doesn’t ??? but i also believe in the Universe— i practice spirituality, all the while believing in the Christian God because that is how things work for me. i have never had a dream of such entities until tonight and i am a bit afraid to go back to sleep because i don’t want to dream it again... if anyone could maybe give me insight on what this could POSSIBLY mean, please please let me know.
