Hi, I like "やばい vabai". I'm not sure it's a slang but it's used in the slang-ish way. You can use when you want to describe anything extreme for example: super hot やばい super cold やばい super good やばい super bad taste やばい super funny やばい It's very convenient word hehe

It is: シーラントは飛行機を雷から守るのに役立ち、さらに空力性能を高めるのにも効果的です。 (Shīranto wa hikōki o kaminari kara mamoru no ni yakudachi, sarani kūrikiseinō o takameru no ni mo kōkateki desu.) Hope it will help you!

ん of どこにいるん is kind of dialect to mean question sentence. If common Japanese, it should be どこにいる？orどこにいますか？

Almost correct but please let me give you more correct one: “Yeah, really, I wonder where we are.” • いや (いや): “いや” corresponds to “Yeah” or “Well” in English. It is often used when the speaker agrees with something or is thinking. • ホント (ほんと): “ホント” is an abbreviation of “本当” and corresponds to “really” in English. It is used for emphasis. • どこにいるんだろうね (どこにいるんだろうね): “どこにいる” means “where we are,” and “だろうね” adds a nuance of speculation or wonder, corresponding to “I wonder” in English. • 私たち (わたしたち): “私たち” corresponds to “we” or “us” in English, referring to the speaker and their companions. In this scene, the character is expressing uncertainty and possibly anxiety or surprise about not knowing where they are.

夢は何を表しますか？ 夢は人間の健康状態が反映されることもあります。 例えば、夜中にお腹が空いた時、食べ物の夢を見るかもしれません。お肉の夢を見る場合は、ひょっとして体にタンパク質が足りてないのかもしれない、洪水の夢を見る場合は、腎臓機能が低下しているかもしれません。 健康を維持したいのであれば、夢にも注目してみましょう。

歩く: (generally) walk 散歩する: walk for health, refresh, etc.

I recommend you do memorization parts such as vocabs and Kanji so you can focus on what you can do only when you are with a teacher during the lesson🔥
