Each encounter im exposed to him more, first time he was hiding and this last time he was running towards me

Location is in mountains in a cabin. Each time is when I sleeping downstairs in basement with my brother and I waking up cause the concrete/rock walls explode

I see the creature come from the hole which looks pretty much like a cavern. And I forgot to mention that after he make rocks explode/cavern appear

There is running water coming from cavern
