Woodland Killer

PLEASE DON'T EDIT WITHOUT PERMISSION. IT TOOK A FULL HOUR OF MAKING THIS! 
I am Jake. I liked Minecraft very much, until a month ago. And the creepy reason is in the story I am going to tell.
It all happened a month ago. I was playing Minecraft with my friend, Jack. And then something terrifying happened. 
I will start at the beginning. It was day 20, if I remember good, when we already got diamond tools and armour. There were 4 things on our list we still didn't visit. One of them was a woodland mansion. We knew it was hard to find one, but we grabbed our food, enchanted our tools and armour, grabbed our potions, checked if we had everything we needed and then.. time to go. 2 Minecraft days later, we found it. We did another check, grabbed our potions and we entered the Mansion. First weird thing was a cross. Secondly, Redstone everywhere. Jack started screaming, I said: You're seeing things bro. But, I saw it too. I don't wanted he got scared. We killed zombies, but we didn't have much health left right then, so we took the safest place nearby and placed our beds there. We clicked it so if we die, we will respawn in the Mansion. But when we clicked on it, we started sleeping. I looked at my clock in my inventory. Shoot, night already. The next morning we started exploring. But I had to go to bed in real. I said goodbye to Jack and left the game. Jack left too. That night, I woke up after a nightmare. In the nightmare, I woke up in the mansion but in real life. The mobs in there said I had to clean the mansion. First remove the blood (redstone), and clean the windows, then take a break, and then I had to kill Jack. When I didn't want to listen, the mobs would eat me. When I tried to kill Jack in the Nightmare, I woke up. I heard something downstairs! I called my parents, but they said I better can go sleep. My parents sleep in the room next to my room, and they heard nothing. I don't wanted to sleep, I wanted to know what I heard downstairs! When I came downstairs, I saw my dog playing with the toy that was always in the drawer. I knew my dog can open drawers, but my dog NEVER played with that toy. I was very tired so I got to bed. The next morning I woke up from my mom walking in my room. "What are you doing here?!" I said. She said the school was closed because the power was shutting down every time, and it was so annoying that the school closed.
That was the moment Jack called. Wanna play Minecraft again? He said. I said yes so we got online. I told Jack about my nightmare. He was kinda scared too. We got on the mansion world again. When we spawned, we saw anything running. It was gone fast. I asked Jack if he saw it too, and yes, he saw it. We were scared. Suddenly, a message popped up in the corner of my screen. It was like this:
<W00dl@nDD_K1//3rrr>: 1 w1// g37 y0U 7W0 4Nd 1 W1// K1// Y0U
We left and asked 2 other friends, Mike and Luke, to join too. They joined. I had commands,so I teleported them to me. The chat was like this:
<W00dl@nDD_K1//3rrr>: 20 N0W y0u 4R3 W17H F0Ur? 1 w1// G37 Y0u 4//
By the way, the O is 0, L is /, A is 4 or @, I is wma E is 3, S is 2, T is 7.
<MikeEp1cBoii>: WTF Is that! 
<I_Luke_MC>: WOWOWOWOW!
So, that was only the chat.
We saw a "player" like this:
Dark brown wood
Glass
Dark brown wood 
Red wool
Cobblestone 
That was what the skin looked like.
He ran towards us, killed us in game ten times in a row, and then our games crashed. The world was gone. I still know the seed, but I think it was not the seed that was wrong. I think every mansion has a chance to be a "Haunted Mansion".
