What are hiding dreams about?

When I woke up in my dream I was standing in a huge grass field with a mansion behind me. My father was sitting in a lawn chair next to me and told me to go hide because the war was starting. I went over to a little bridge with water underneath. Grabbed a bucket and got into the water with the bucket over my head. I stayed there for about 5 mins. I remember hearing my breath in the bucket and feeling cold from the water. When the 5 mins passed, I got out and my looked for my dad. When I found him, he immediately told me to go back to the water because round 2 was starting. I grabbed the bucket again but before I had the chance to get into the water, a woman grabbed my arm and pulled me towards the mansion. She explained that "I wasn't supposed to be here." She led me to a very tall man in a blue suit. He took me to the front lawn and pulled out a gun. He told me that I can shoot myself or he would do it because I needed to leave. I decided to do it. I put the gun to my head and pulled the trigger. All the sudden bright lights were around me and I started floating. I felt so warm, like nothing has ever affected me before. It was actually an amazing feeling. I slowly woke up from this dream. Not panicked at all.

But I'm truly curious as to why I didn't wake up once I pulled the trigger? Also, No part of me is suicidal.

I was with my first love for 7 years, we were basically kids. We stopped dating 3 years ago and I met the man I am with now 2 years ago. The man I am with now just purposed to me and wants to marry me.. I still talk to my ex from time to time just to see how hes doing and we cut off the conversation but he always keeps in touch. Last night I had a dream that me and my fiance moved into a big huge penthouse and my ex showed up to my window with a letter and I took the letter and my fiance kicked him out. I began to read the letter and I couldnt fully read it because I was hiding in my closet so nobody can see me, but most of it was a letter he wrote to me asking for forgiveness and how he regrets what happend to us and truly is in love with me. The dream then jumps forward to me and my fiance in this new house still and its such a luxury home and thats not the life we live right now. In this dream the new penthouse still made me unhappy. I was overall unhappy with the house and everything my fiance was buying for me. I had the biggest closet in this dream with all the expensive name brands and I was still unhappy. The dream jumps forward again and my ex comes back and I let him in the house while my fiance is sleeping because I wanted to know what the heck he wanted.. then I woke up

I had a dream about my family not accepting me because I am gay so I started to cut my throat with a knife but then decided to stop and kill my mom instead. I cut her with the same knife.

And then I was a baby cow eating pudding in a supermarket while hiding from an evil wizard.

What the fuck is even going on here? Where did this violent part come from? Why did it shift to nonsense so quickly?

It was a school meeting in an auditorium, in which the staff believed one of us was hiding something inside ourselves, and to find it they had to cut open a part of our stomach. The woman who sat beside me was getting cut open, and she gave the impression that this was something she was used, based on how unfazed by any of it happening to her, as I saw her getting stabbed, and handling it with pure ease. It becomes my turn, and I start to panic. Despite my frantic act, the lady (staff member) began to start cutting my stomach open anyway (using a pair of heavy duty scissors). I began to try forcing myself to deal with the pain, but it became unbearable, to the point where I starting screaming and threatened to hit her if she would stop.

So it was a pretty normal dream, taking place in my hometown in present time. I was walking home like any other school day, but something was off. There were weird things around, like certain roads that weren't supposed to be where they were, and most notably, a Sakura (cherry blossom) tree outside of a house I always walk by that doesn't have a tree in front of it. I didn't notice it though, cause it was a dream. Anyway, I must've taken some kind of detour, because I ended up in a field, that's usually on the other side of my neighborhood. This is where the weird shit goes down. So throughout the dream I was occasionally seeing this (yes it's hilarious thinking about it) really off-putting man in a banana costume, hiding in weird places (now that I think about it, only the ones that were out of place). He had a new expression each time, and he looked more and more deranged as time went on. So when I reached the field, the sky had already turned dark, so It was night time. The field is surrounded by houses (it's in the middle of the suburbs), and the playground that's usually there is no longer present. All that was there was the washrooms, in a building in the center of the field. I don't know why, maybe to hiding from the banana guy (I was starting to get the idea that he was following me). I walked in, and went to wash my hands, when to my left, out of the corner of my eye, I saw him. He was laying limp on the toilet in the stall across the floor, with his head hanging in front of him. He had the most deranged and twisted face I'd ever seen, and he slowly turned his head to look at me. In classic SCP-173 fashion, I tried not to break eye contact, but I couldn't look at it for much longer because I felt like I was going insane. Making sure not to make any sudden movements, I slowly began walking towards the door. The banana man (stop laughing) was starting to half cry half laugh, slowly getting louder and louder. He was no longer in my line of sight, and I felt like any second he could've just gotten up and started chasing me. I felt SO threatened. Terrified, I started to crack the door open, and I was sure that he was going to run up behind me at any moment, but he didn't. He just sat there. Once the door was halfway open, I flung it the rest of the way open, and made a break for it. It was pitch black out, and I was alone. I was too scared even to scream for help, so I just kept running. The laugh/crying transitioned into angry screaming, still laughing all the same. I didn't look back to see if he was giving chase, because that would've slowed me down. The houses around the field were gone. All that was left was an endless open field. I stopped running and turned around, to find that the screaming was gone. Still, I felt no less afraid. All of a sudden, I heard footsteps behind me, and I turned around again, but nothing was there. The screams were coming back. I fell to my knees, panicked to the point where I couldn't keep running. The screaming faded in quickly to the point where it was deafeningly loud, and I started screaming too. That was when I woke up.

Bananas freak me out now. Thanks, brain.
