Take the minecart deeper, leave a diamond to mark the spot

As you start to roll, you hear a shriek in front of you as become swarmed with bats. Suddenly you feel another figure in the cart behind you that gives off a blue hue

Turn around and see what it is

There is a ghost with a headlamp who looks terrified.
You see agony in his eyes and tries to mouth something as he disappears into blue dust

Ok, stop the cart and tgo back to the general place where the ghost apeared

When you get back the ghost is sitting there, crying and is giving off a dark blue hue, making him hard to see

I attempt to talk to the ghost

He looks up scared at first and his face softens when he realizes its you. He stands up and tries to talk to you with a happy expression on his face but when he realizes he can't speak, he sits back down and covers his face

Can we use gestures

Yes

He looks up slowly and tries to draw something out in the dirt and coal dust
