When I first got Minecraft in 2011 I didnt do much but create pixel art, this particular world I abandoned after 2 days or so.
    I remember that I was going to make a sprite of my skin at the time but I stopped because I was currently studying for my finals, I didnt play Minecraft for at least a month (I forgot I owned it). When I started playing Minecraft again I started focusing more on my Mincraft architectural skills so I rareley even thought of opening any of my pixel art worlds. But today was different I decided not to expand on the cottage I was working on and go back to my old worlds so I went back to my main pixel art world. When I jumped in there was nothing besides the frame of the sprite and a portal-like frame made out of coal blocks (wich we couldnt have yet). I was quite curious how this appeared, I havent played it in 3 years and I dont know how this ever appeared. 

I do think my Minecraft is haunted...


Someone please help explain...
