Translation of 白日 by 大象体操

I am a beginner in Chinese, but I would be thankful for the mountain of corrections I will receive :)
The order below is chars, pinyin and then my attempt at an English translation. I would also be thankful for any advice on any words that aren't particularly normal or common :)

2.白日

今天我松松的 做个梦 Jīntiān wǒ sōng sōng de zuò gè mèng - Today I had a loose dream

Here 松松 does not mean "loose", it means you are carefree, at leisure, unfettered, with ease etc. So the sentence translates as, Today, a dream came to me easily.

踏着白色浪花 冰冰的 tàzhe báisè lànghuā bīngbīng de - Inspired by the white ice spray

踏 means "to step on" 着 is a particle functioning as a continuing state, like the "ing" in English to change a verb into continuous tense.  浪 means wave, 花  means the foam as they like flowers (poetically speaking) Hence, stepping on the snowy white cold foam of the waves

是谁在说说话 像唱歌 shì shuí zài shuō shuōhuà xiàng chànggē - He/She who likes to talk, likes to sing

谁 = who. 是 = is, are etc. Repeating a character is like 着 to indicate a continuing state of action.  像 = like (as in similar to).  Who is talking, as if in song

翻个身我看见 影子摇啊摇 fāngè shēn wǒ kànjiàn yǐngzi yáo a yáo - (Not sure at all)

搖啊搖 is same as 搖搖.  The particle 啊 functions as a pause, something like the English "Oh".  In other words, the action continued and the stopped for a quick moment before continuing.  As I turned, I saw a shadow, swishing, swishing...

我是我自己的宇宙 wǒ shì wǒ zìjǐ de yǔzhòu - I am my own (or in my own?) universe

安静地在自己里诞生 ānjìng de zài zìjǐ lǐ dànshēng - (Not sure at all)

地 here does not mean "earth" but a structural particle that functions like the "ly" suffix to change the verb into an adverb.  In linguistics mumbo jumbo, "It used before a verb or adjective, linking it to preceding modifying adverbial adjunct" Quietly I was born within myself in other words, "to renew oneself"

生长成树或一个山洞 shēngzhǎng chéng shù huò yīgè shāndòng - Grow into a tree or a cave

I grew into a tree or a cave,

或一阵忽然的风 huò yīzhèn hūrán de fēng - or a sudden burst of wind

or as a sudden gust of wind

我是一只长不大的虫 wǒ shì yī zhǐ cháng bù dà de chóng - I grow up as a worm

I am only a insect that won't/can't grow into adulthood. He dreamt that he is an insect and obliquely about his own insignificance

缓慢地抬头看着天空 huǎnmàn

de táitóu kànzhe tiānkōng - Slowly and unhurriedly, I looking up at the sky
世间万物都那么的大 shìjiān wànwù dōu nàme de dà - Everything in this world is so big  

于是我唱出声 yúshì wǒ chàng chū shēng - Therefore I sing out in words.  "Sing" means to make a melodious sound.  It has the same logic as the title of the song, "The Sound of Silence" an oxymoron in meaning but logically correct. 

Thanks!
