What's being in a coma like, and how did life change afterwards?

My friend told me that while he was snowboarding, he hit a tree, fell unconscious and was airlifted to hospital, and in a coma for two weeks.

While he was in a coma, he remembers walking in a field, a wolf by his side, walking towards a tree in the distance.

For days, he wasn't getting any closer to the tree, then suddenly

he and the wolf got closer and closer until they were at the tree. The tree was beautiful,

and it had a face, but the face kept changing faces, from people he had met in the past to people

he met later in life. The tree reached its hand out toward him and was holding a key. He grabbed

the key from the tree, held it to his heart, and the wolf disappeared. The tree reached its hand out toward him and was holding a key. He grabbed the key from the tree, held it to his heart, and the wolf disappeared.

The tree disappeared and he woke up.

He now volunteers in a wolf sanctuary.

I can't remember where, but I've heard similar stories.

People climbing stairs endlessly, trying to reach an island by a boat, waiting for a plane to land.

Only when they got to the top of the stairs,

reached the island or the plane landed, and they got off, did they wake up? Honestly, still feeling

the after-effects some seven months later. I always feel high, like a piece of me is gone and won't

come back. I spent the first six weeks after waking up wondering who I was. I've been diagnosed with depersonalization, derealization disorder.

Look into it, there's a lot of us out there.

It's so hard sometimes to get through it.

I wake up every morning wondering if I'm even real.

No one understands, and they just give me Xanax to deal with the panic attacks.

Walking in woods really helps me a lot and just trying to be normal

and doing things you used to helps. But there isn't a day that goes by that I don't feel like
