What are decapitation dreams about?

i was on the beach driving my jetski, my phone rang and i answerd it was my dad, he told me to go to the blocks nearby becouse there was a sucidal woman, i went, the block was derteriorated half of the top  wasnt there, i climb as fast as possible to her apartament to find her standing against the guardrail of her balcony, luckly i talked her out of it, she got away from the guardrail and came closer to me, she hugged me tight, i remeber the red dress she was wearing, after that some men came and took her to a prison/phsyc ward, i went to broke her out, i got there and we met in the yard we talked our plan and made it happen the first time it didnt work but the seconth it did we were out our pants got ripped when jumping the wall, she looked down at her feet and saw a mark on her leg, it was like a pentagram not just a bruise or something, we got scared ao we went to a witch as i had one aswell, (i wake up after this and fall back asleep) i now find myself in a apartamnet crying, it was my mom aparrtament she asked me why i was crying and i told her, that i cant find my love the woman that i saved, she then took a beer can and used the sun to reflect light in her window, she came outside on the balcony and waved her hand, as fast as i seen that i was running down the stairs to get to her block my brother was also there and he did the same, i do not get to arive at  her block though, couse she did the same we met on the bridge, my real life real life crush was there, even tho she was there i run at the woman dressed in red hugging her thightly while shes doing the same, my brother hugs my real life crush,  this hurt me in a way but not so much becouse the woman dressed in red holds me thight as i do the same (everything goes black)  we find ourselves on a ship i think, me and the woman dressed in a red dress, we were fighting the men from the same organization that took her in the pshyc ward, we were in a room with 2 doors one in front of us and one lined with my sholder, i open the door at my side, it was dark inside it seemd like sonething was in the corner, scared, i close the door very fast, then she opens the foor in front of us, inside were  5 men armed with ak-47's (i think) four of the men ran and jumed off the ship in the water, the last man dashed to the room i opend previously i go after him pinning him to the ground and start hitting him with a "this way" arrow signs (i dont remember very good couldve aslo been a car license plate) i hit his neck multiple times wich decapitated him, i remember very well the blood staining the white fuzzy carpet that was in the room, as i mentioned earlier there seemd like there was something in the room, it was, there was a small dog that looked very much like my reallife dog named tina.

i wake up after this very mad about not being able to fall back asleep and continue my adventure with the woman in the red dress

The dream was simple and very disturbing. I was on some unknown train station where people were putting their heads on railway rails so that next train would decapitate them. The first few people trying to die this way were pulled away by the ones who were nearby and therefore saved. But there were many more such attempts and nobody seemed to care at that point so people were just taking their lives put putting their heads on rails.

That's quite a nightmare I must say. It's disturbing to say the least.

I really can't remember the first part of my dream but I remember looking for something or someone. I ran towards a room when the door suddenly shuts and a little girl/boy (color gray and looking disheveled) appeared in front of me. I screamed for my mom, and my mom was able to open the door. She was frozen in fear when she saw the child and couldn't enter the room. I'm not sure why I suddenly got mad and picked up a shovel or something and attacked the scary kid. I was able to decapitate the kid but the head was still able to speak. It said "I am the demon of death" something like that and I got angrier and tried to mince the head further but now every time I attacked it I felt my breathing being constricted. It felt harder and harder to breathe and felt something was on my chest but I continued to attacked it until I woke up. I'm not sure why I dreamt of something like that. Does my dream have a deeper meaning? What are your thoughts?

It was maybe 6 months ago when I had a vivid dream of finding my professors dead body in school. He was decapitated and bloody. I didn’t kill him but I was not thinking straight and thought they’d think I did it so I hid the body by putting it in a trash bag and dumping it. They found the body the day after and I was lucky there were no cameras at the basketball court where I found him. They did an investigation and I was in no way linked so I wasn’t questioned at all. I guess they didn’t check the cameras by the hallways because that’s where I passed to get the mop and clean the blood.

The thing is, I thought this really happened up til this day. I’d be up all night thinking what I have done and scared that any minute they will find out I did it. It wasn’t until this day that I dreamt in the same universe again, where it made national news and they kept on looking at the culprit that I realized nothing made sense. We’re in a pandemic and I haven’t stepped in school for the past year. I don’t even remember who’s body it even was. I just remembered it was a male professor I know that I knew.

I know I sound dumb for not realizing until now and bearing the weight of it for 6 long months but you have to know that it all felt real. I was constantly thinking of it at night and I blocked myself from national and local news to ease my paranoia.

I was in this luxurious beach house, Everything was shining and white, i was playing on a console i Always wanted to play on, it was raining very heavily
While the house played a litlle tune, i can barely remember it, but it was calming

Then the view switched to outside the house in a nearby street, i was running  away from a flood  alongside a tall girl and a cartoony girl  dressed in a black dress (just imagine a bell with a circle on top of it) when suddenly the girl in black few, slid across the street and her head got decapitated by a random wood shard, strangely there was no blood, then the flood hit us

The view switched back to shiny beach house me, i was playing with a charger when i suddenly i  looked at the window,.there was a huge flood wave, with myself, the tall girl and the small girl who was somehow stitching her head back up in the wave , beach house me embraced for impact, the glass shattered

And then I woke up

any sort of meaning that could be extracted from this?
