The NPC Village

The story started when I was playing old versions of minecraft.Since minecraft was beta.I always remember that one server that I always used to play on singleplayer.So I tried getting in the server and it worked.I remember it was an NPC village,old NPC vvillage.So I started wandering around a bit.I went to see the chests. In the little huts,but they were empty,but I remember that I left something in those chests.Eventually I found a chest that had some useful things.there were no villagers (p.s:old villagers had a steve skin),then I went to kill some animals for food.Then I felt a presence behind me.I turned around and I found a villager behind me.he told me "can I assist you" here is the conversation,but till now I dont know if he is an NPC or a player

WARNING:LONG CONVERSATION AHEAD.

Me:hi

The NPC:Can I assist you?

Me:Are u an NPC

The NPC:do you need assistance

Me:are u real?

The NPC:Hello there,traveller

Me:WTF

The NPC:It's dangerous out there at night

Me:ARE U REAL?

The NPC:Hey.........,Ryan

At this moment I was horrified.How did he know my real name.It was like you enter pizza hut,AND THEY DONT HAVE ANY CHICKEN PIZZA I AM LIKE "ARE U SERIOUS PIZZA HUT,THEN WHY IT IS IN THE MENU"ehm back to our conversation

Me:WTF,how did u know my real name!?!?!

The NPC:Can I assist you?

Me:NO

The NPC:Soon it will be night,you better start seeking shelter

Me:SCREW THIS

And as I was walking away the NPC said something that made me freeze from the top of my head to my feet

The NPC:No one can save you

Me:What do you mean!?

Then there was complete silence for about five minutes then it said

The NPC:Can I assist you?

Me:Wtf,WHAT DO YOU MEAN FOR GOD SAKE

The NPC:IT'S too late.

Me: u know what?I dont care!

The NPC:It's over

Then I realized something that made me completely freak out I am playing on single player how is he an NPC if it writes in the chat ,At this moment I was shocked,I couldnt move I felt like they were very heavy

Me:how did u get in the world?

The NPC:Do you need assistance

Me:How long have you been here

The NPC:You should seek shelter traveller,it is dangerous at night

Me:ANSWER MY QUESTION

The NPC:987 days

I was shocked,That guy or NPC had been here 3+ years

Me:How did you get in here?

The NPC:it is dangerous at night

At this moment it was starting to get night,I waited a couple of seconds, then he started to move

Me:where are you going?

It didnt answer,it just kept walking and I couldn't hit him or hurt him so I thought it was an NPC

And at old minecraft versions it gets really dark at night ,And he stopped in the middle of a forest suddenly

these were the last words that he said

"IT IS YOUR TIME"

"I WILL TAKE CARE OF YOU"

"IT IS OVER,THERE IS NO MORE FORGIVENESS"

"ITS YOUR TIME TO DIE"

Then my game crashed then suddenly the lights went out there was complete darkness I waited in my place for about 30 minutes but they felt like 30 years then I saw a shadow moving in the dark I was frozen all I could do was to pray for god that he goes away,and eventually he went away I waited 10 minutes in my place to realize what happened ,then I went to check outside and he wrote on the wall with blood

"PREPARE YOUR ANUS"
