IAmAlisa2840

CHAPTER 1: SEED 2840
I started playing minecraft a few weeks ago, and I wanted to play in seed 2840. I opened a LAN World with that seed because I wanted to play with my classmates. They entered, and their nicknames were Antik2586 and the other was Alofa0379. Alofa entered first. We started playing because Antik was going to be late for some personal reasons. We made a small house with Alofa. He and me started to make a house together.. While we were building a house, house's blocks changed when we got away to get more items for completing the house. I collected 64 woods and he collected 64 cobblestones to build a ceiling to our new house. I went to collect some food. I was walking around in forest, I found some sheeps, but they were running from me like actual players. Running, jumping, and attacking like players. While I was running after the sheeps, I saw almost 20 of wither skeletons. We didn't ever build a nether portal so it was impossible. They were almost like wither skeletons were there to help to sheeps. But while wither skeletons were attacking me, they all died at same time and all of sudden. I noticed there was a small land from sands on water. I swam to this small land and saw glitched blocks on there. I got scared and left the world there.
 CHAPTER 2: THE SERVER OF ALISA
I entered to a server after a while when these events happened and lasted. I don't remember the server's name. Some signs welcomed me with a bedrock box in spawn. I typed in chat to see if anyone was answering me. But when I realized even when I enter my text into chat, it wasn't showing up in my or normal chatbox. And just then, I decided to read those rules that were on signs. The rules were pretty simple:
1) Don't mess with buildings you see. 
2) Don't kill any mobs that acts like players.
I thought they were easy. How could two rules that simple be so hard after all, right? Trust me, they are. I did read these rules, and went to collect woods to make a house. And when I did, a few wither skeletons came and started attacking to me like actual players. They were pvping like actual players. And I did a 3v1 for that event. When I died, I respawned in a box that made with command blocks. There was a girl with me in box, her nickname was IAmAlisa2840. She was something else, she was walking around ignoring me, just like she was the owner of the server and command blocks. She typed into chat: "How did you get here?", then I responded: "I just respawned here.". But my text didn't appeared in chatbox again. But she said "okay!", as if she could watch my screen or see my text. Just then she and put a lever on a command block and asked me to pull the lever. I pull the lever and I got banned all of sudden with a text saying that "Rule one is violated: Never mess with builds you ever see.", but still, I didn't and don't understand how is pulling a lever is banned on server...
