Minecraft survival episode 2

I don't know if this is normal but I found a disordered cross in the world and I decided to go investigate, I went past the cross and saw a pit and going near it my game crashed and I loaded back into the world again and found I was in a different spot from where I was before the game crashed, I didn't want to go back to the pit again so I went to the soul sand and other stuff, but then random arrows started shooting at me and it was very.... creepy,
