Something weird is going on in this odd world

=== Info for it ===
I just put up a seed in it, I am not going to say what the seed is. There are no pictures because I don't know how to take screenshots. But I do swear that it all really happened. A part or two may be a bit exaggerated.
== Prologue ==
1/7/2021, starting at 3:17 PM and ending at about 4:20 PM.(I made this on 1/8/2021 but it happened on 1/7/2021). When I put in the world, I thought it read for a second something different, just 1's and 0's in the seed even though I had put a word in the seed. Once it loaded, I saw I was in a Taiga forest with nothing out of the ordinary. I know that you need sheep, and I like the Taiga because you don't have to hunt for sheep, wolves just do it for you. I saw an adorable baby wolf with a few grown wolves nearby. I just made my character appear to nod it's head. After a couple minutes of playing, I found two piles of mutton and wool next to each other. Nice I put through chat for no reason except that I had two pieces of wool and some mutton. I had cut down a full tree, and most of the time I spawn on the trees for some reason. 
That was when I thought I saw an orange blue whizz past me. I looked at where it had gone and saw nothing out of the ordinary. I had crafted all the logs into wood, and I had gotten a total of 16 logs, so I had 64 planks or a stack. I had also crafted some of those planks into sticks and a crafted table and then placed it down. I crafted a pickaxe on the table. I was right near some mountains, but I don't think there was enough mountains nor were they tall enough for it to be considered an extreme hills biome. I mined out some stone and headed back to my crafting table and crafted three things; a stone pick, a stone sword, and a furnace. I found a sheep and killed it. But strangely, when I killed it, it turned red and fell over like normal, but then it stood back up still red, and attacked me. Luckily a nearby wolf sensed it and came to my aid and it killed it, and it acted like it had actually been killed, and then I collected its wool and mutton. 
I got back to the crafting table, and crafted myself a bed. I broke the crafting table and got in between some of the leaves on a tree. I broke the leaves so I could stand, and I remember that in 1.15 or 1.14 you couldn't place a bed on leaves, and I don't know about now, 1.16. 201 I think? It may only be 1.16.101 or 1.16.200 still. That made me place some planks down and then the bed. It was just after sunset, and I began sleeping in my bed. Just a few seconds later I woke up, at morning for Minecraft. (Though not actual morning) I went back down and saw a few bones from a skeleton that had either burnt up, or a wolf killed it. I went to a wolf, and used two of the bones, and then a third and final, and he became tame. I have decided to call him Sed, and I might change that. Okay, I probably will. I didn't actually name him since I didn't have an anvil. I went back at the mountain and mined until it was night. I went up to where my bed was in the forest, and then my wolf TP'ed to me. (Teleported) I slept again.
After a few days of work, I began to make my house and then finished. It is tall and I can see a huge area around where it is. I guess this is the end of today, and I did chapter one just before I started writing this. I'll update later.
== Chapter 1: The Great Chamber ==
1/8/2021, about 9:50 AM - 11:00 AM. I had completely finished my house now, and was trying to figure out how to throw a stick to play with Sed. Then I remembered that in Minecraft, dogs don't care about sticks. I could throw it, and he would just stand there, like, what the heck are you doing? I had gone back up into the top floor, which was really just for watching.
I saw an orange blur out of the corner of the screen, and turned towards it. I could see the orange blur running very fast towards my house. I thought, OH CRAP. I headed back down and brought my dog onto the top and then sat him. I headed down and replaced the spruce door with some iron ones that I had gotten and a minute later, I heard the sound of thumping. I looked at the door, and saw cracks starting to spread. I began to panic, and then turned on discord and then said, panicked, "What are you doing?" The cracking stopped spreading and then disappeared altogether. I jumped when I saw a message go through chat Why are you so panicked? I started walking around, and then walked onto the same floor with Sed. I heard a large explosion. I walked back down to the first floor, and froze. The entire first floor had been blown up. I looked around and saw that the orange creature, was long gone.
I left My wolf out at my house, then started exploring. I headed north and found a desert, with a temple in the distance. I went back and then headed east, and saw a small grassland village. but then I headed west, and saw a large stone brick building. I headed towards it. I soon arrived and looked at the doors, which seemed to be made of Bedrock. There was a 3 by 3 of buttons next to it. Oh, a password I realized. I started putting passwords in, any that might work. Soon I had put in 32 out of 45 combinations, and the doors swung open. I went through and gasped when I saw the size.
It was really big, and there were 4 Stairways. Two went up, and Two went down. I went down the first one. I was now in a passageway. It was 2 blocks tall and also 2 blocks wide. It was very long, and there were also other passageways branching off this one. I went down, and soon got lost in the maze. Soon I realized that each passage, had a trap. I soon had found a room with stairs leading even farther down. I went down, and it seemed like it just got longer and longer. Soon I was were bedrock should be, but it kept going down. Soon I was in a chamber, that was definitely a meeting chamber with a hole at the center that went down to the void. After a while I managed to make my way back home. 
It looked like it was completely destroyed. Where it used to be was a large flaming crater. My wolf was whimpering, just out of the hole, but had definitely taken a lot of damage. I will wright more later, but for now, I needa take a break from writing this. 
== Chapter 2: The Void and The Desert ==
1/8/2021 (Time is not going to be included anymore) I walked towards the Desert with my wolf. I had healed him and soon, Sed and I were at the desert. After more time we got to the temple. The 'Ankhs' on the side seemed to be changing color before my very eyes. I headed into the temple and found what seemed to be mummies. I managed to kill them.
I carved a way down to the chests. I opened one, the only one, there had also been no pressure plate. It was what looked like an enchanted book, but it was a signed book. I headed back up, and found at least thirty more Mummies. They were all in paper wraps, I think it was paper. Every other one had some sort of gold thing, though one was tall and it had a gold chest plate, helmet, leggings, and boots, and a diamond sword. It also had a health bar, and the Title was Boss Mummy. 
I fought it for several minutes, and finally killed it. I was about to head outside to my dog, and then I stepped on a pressure plate. I fell down a hole into a pit of water. There was bedrock everywhere. I realized I must be in the void. I just started wandering on the bedrock, and found a door literally made of bedrock. I tried to open it, but a message went through chat that said that I must find the bedrock key. Soon I found some iron doors, and the message was an Iron key instead of bedrock key. Soon I had found some spruce doors, and tried to open them, expecting it to say something about a spruce key. Instead, they swung right open. I walked around, and soon found an Iron Key. I ran towards the iron doors, and unlocked them. To be Continued.
== Chapter 3: Behind The Iron and Bedrock ==
Through the iron door, there were hundreds, hundreds of bedrock keys. They were teleporting everywhere. I left clicked on all of them, and finally instead of disappearing, it appeared in my hand. I went towards the bedrock doors and unlocked them. There was soul sand and water. I went up the water, and just when my oxygen was out, I got to the top.
