Always day dreaming in the class, till I don't even know the lesson's done

课堂上总是打瞌睡，直到我竟不知早已下课了。

Okay, we gave you every tween girl's dream day, and-and you can barely crack a smile.

我们给了你每个少女梦想中的一天，而你笑都没笑一下。

I was so carried away by my day dreams and thoughts that I didn't notice that Cindy had arrived.

我被我的白日梦和思绪冲昏了头脑 以至于没有注意到辛迪已经来了。

Ahm, well yes, I usually remember my dream every day but I forget it so I don't really remember it now.

嗯，对，一般我会记得我每天做的梦，不过现在我忘了，所以我现在并不记得我做的梦。

Do not spend any time in day dreaming or castle building; hold to the one vision of what you want, and act NOW.

不要将时间浪费在做白日梦或异想天开上，脚踏实地的坚守属于自己的信念，并且立刻行动起来才是正道。

It's not really an obsession, it's when you like, look at it, you feel like, quite dizzy and you go on day dreaming.

这并不是一种痴迷，而是当你看着它的时候，会感到头晕，然后继续做白日梦。

It mixes two senses of the word 'dream' - what happens when you're asleep, of course, and the sense of day dream or reverie - it's a very general use.

这里采用了dream的两种意思——当然，其中一种是‘睡觉时发生的事情’；还有就是，白日做梦——这种用法很常见。
