My Brother Is Constantly Going To This Dangerous Place

So, recently we've made a pack, and been telling each other secrets. He started telling me that he doesn't know what to do about this "gift". He started telling me some of his experiences. One I'm really concerned about is this:

He's going to sleep at night and going to this place.

The place is very dark, and it changes a lot.

The first time:

He's walking and he's glowing, asking himself "Why am I glowing?" He sees a green light, he walks toward it. Then something jumps out lashes out at him and throws him to the ground. A bunch of these "things" claw at his stomach. He wakes up, sweating, and he has light claw marks on his chest. He says they're not crescent moons.

I don't know if he's scratching himself or this "thing" is calling him to it.

The second time:

Same place, same light, still glowing. He remembers last time, and starts to cry. Nothing happens. He got up, and started to walk towards the light. He trips on something. He starts to crawl to the light. The exact same spot where he was thrown to the ground, something jumps over him, he gets up. Runs toward the light. Right before he reaches it, he gets tackled. Him and the "thing" both fly through. The "thing" is in the light now, he can see it. It doesn't have a gender, It's black, It screams at him repeatedly to "help it". He doesn't instead he runs the opposite direction. Now he's in a jungle, he sees something in a tree. He climbs the tree. He wakes up, sweating, with claw marks.

Now I'm thinking what did the creature want?

Third time:

Same thing, He ducks when the thing jumps over him, when he gets tackled usually he drops to the ground. He runs to the jungle. He recalls when he woke up last time, in a fit to get out, he climbs the tree. When he gets to the top, he reaches for the branch, of when he woke up. This time something pushes him, he falls to the ground. He falls for a long time. He sees floating islands, with different colored light blobs. Then he hits black snow on the ground. He smells sulfur. He can't breath. He feels like he's immortal. Being tortured, not being able to die. He starts to walk, reaches the jungle again. This time he sees a "heavily breathing creature" He sees his dad, who doesn't live with us. When he sees him, the "creature" starts to breath and spits on him. He wakes up, sweating, with claw marks.

I think this place is dangerous, is there anyway he can stop from going there?

He also says that before he goes to sleep he thinks this involuntary:

The sweet spot.

Fourth lumber down.

Adominal area.

The blood has a metallic taste.

What does this mean? I'm so lost. And I don't want him getting hurt. This shouldn't be how he comes into his "Gift". Mine just started with prophetic dreams.

Is this a dream? A calling? The gateway? I'd like to know...

Thank you for your time.:)
