The first few lines aren't much to go off of, its better to post the entire chapter. I can point out
how it fucking sucks a couple problems though.
I sat cross-legged as the cold from the soil reached up to me; waking me out of my thoughts. I’d first think it was just a dream, something that i could wake up from but not anymore. As i saw the sun move, reach out and climb its way down, my heart grew cold along with it.
The start has very little impact, these are things you're better off leaving a couple lines later. This is a first person perspective, try starting out with the thoughts he was 'woken up' from.(this is very poor word choice, since its not exactly a state he has to wake up from. Try something like 'detracting'). You also used the semicolon incorrectly; a regular comma is appropriate for this sentence, since it's not linking two sentences that can stand alone.
Second sentence, "I had first think it was just a dream",
think -> thought. You started off with past-tense, keep it consistent. "something that I could wake up from
, but it wasn't.
not anymore(this implies he has woken up from a situation like this, has he?).
Third sentence. "As I saw the sun move, reach out and climb its way down, my heart grew cold along with it." Might be my personal preference, but this idiom doesn't really make sense. You put too much actions, and describe very little of the sun. Maybe it could reach out with rays of light, or climb its way down from the clouds. The sun didn't grow colder, the air around him did... unless you're going for a fantasy type of sun that's a giant lightbulb.
The wind was blowing from my side, causing the slow rustle of the leaves and the calm chirping of the bird which left me in a daze. I would have found it relaxing if not for the current situation.
Rustle -> rustling. to keep it consistent with the rest of the sentence. Additionally, its implying that the chirping of the birds was also caused by the wind. You can try moving that part to another sentence. "That, along with the calm chirping of the
birds/a bird(since it is not a very specific bird that's important, I hope) left me in a daze.
How did i come here? Despite my memories being vague and all over the place, i knew for a fact that i was not camping in the woods. So how?
Come -> get, 'come' is present tense, you're writing in past tense. As for the rest, you should try portraying his memories were vague and all over the place, cause the previous lines do not suggest that whatsoever. You wrote everything more like a third-person limited instead of a first-person perspective, try to take advantage of it and get the reader more involved with the thoughts of the narrator.
That's just my 2 cents, from the little info we got from these paragraphs.
