Une conversation au téléphone.

Ce matin, un ami m'a téléphoné.

J'étais surpris parce que je n'avais pas bavardé avec lui depuis janvier. Il habite à Madagascar et j'habite aux États-Unis. Ainsi, il visite New York pendant un mois avec sa femme.

C'était drôle quand il m'a téléphoné car il parle (la langue) Malgache avec moi. Je n'avais pas parlé Malgache depuis janvier. Au début, j'étais surpris et je ne pouvais pas parler Malgache pendant une minute. Mais, après ça, je pouvais le parler.

C'était un beau matin après notre conversation!

Our Amazing Brain .

I believe that the humain brain has extraordinary abilities that scientists haven't discovered yet. Actually, there are phenomenons that we can't explain yet, like presentiments, intuitions and some complexed feelings we can have.

For example, I once accidentally heard a German song, knowing that I neither understand or speak German. I started crying to the lyrics of that song. I felt something strange in me, as if that song touched something deep in my heart. It was absolutely strange since I didn't even know what the song was about, so I searched for the translation.

It was actually a story about two people who fell in love while waiting for a bus. They kissed each other under the rain. Then the girl took a bus, and the boy never saw her again. 

A touching story indeed, and I feel confused about how my brain interpreted it or somehow understood it.

One other thing, how can we explain the intuitions or presentiments?

It's a wide complexed subject, in fact.

I bet everyone, for once at least in their life, felt bad or not comfortable about something or a decision, so they avoided it, and in the end, it showed that the thing or the decision had bad consequences and results.

So how can we explain that the brain even knew the wrongness or the badness of a decision or a thing before it even happened or been taken?

It's good to see that you're using line spacing. It does really help your writing for both appearance and expression.  You do need to be wary of your comma use and learn when to use the period (or "full-stop"). A comma is used for slight pauses usually.  If two statements are independent clauses and are not separated by a contraction, then use a period (a comma just won't do).  This was overall great! 

New Life in NM

In This summer, I started a new life.

I do not know how to describe this feeling. I moved to America, and changed my name that no one called me before. Sometimes, it is like a dream. I have to take classes everyday, talk to people each person, eat different kinds of food, and socialize with people who come from different countries. I feel that something is changing in my soul.
I made this decision, so and it changed my life. If I never didn't do that before, I could just be an engineer in Taiwan, doing repair and debug work everyday. Most people live in their country until they die. But if one day, you have a chance to go to a different country, you will know that is a totally different feeling in your life.
Because I chose this way,  so I started a new life.

It's overall okay.  Some difficulty with the simple past tense.  It can easiy be fixed.  I tried not to do too much alteration to your writing. I hope this was helpful.

Good luck with your stay in the U.S.!

J'arrive pas à dormir!

Mes yeux sont ouverts et ils refusent de se fermer.

J'essaie les fermer en ordre dormir mais ils ne veulent pas.

Pourquoi ils refusent ma simple demande? Est-ce qu'ils me detestent?

Pourquoi moi?!
