What does 「Nounを笑え」 phrase mean in this sentence?


> Oh! KAREN 浜辺の濡れた砂の上で  
>  抱きあう幻を笑え

It's from a song 「恋するカレン」by 大滝詠一. Lyrics
[here](http://j-lyric.net/artist/a001134/l0118f0.html).

Based on my understanding, here's my translation:  
_Oh! KAREN I laugh at my dream of embracing you in my arms on wet sand on the
beach_

Would "laugh at" something be the appropriate or close enough meaning for
Nounを笑え. I say "laugh at" because searching for「〜を笑え」showed up this sentence
in the search results (as title of one of the youtube videos)

> Laugh at life～人生を笑え～

宜しくおねがいします




笑え is the _imperative_ form of 笑う, so literally, it's not "I laugh at my
dream" but "Laugh at this dream I had (until now)!". It doesn't make much
sense for him to tell Karen to laugh at himself in this context, so I think
he's saying this to no one in particular (or, to the listeners of this song).
He's describing how silly and laughable his 幻 was.

Also note that ～ **を** 笑う is somewhat special. 笑う is usually an intransitive
verb (～ **に** 笑う / ～ **で** 笑う). The transitive usage of 笑う (～ **を** 笑う) has a
scornful/derogatory overtone. You may want to pick a more negative word to
translate this ～を笑え.

> When used as a transitive verb, 笑う means "laugh at~~" in the sense of
> "ridicule" "deride" "sneer at~~" "make fun of~~".

  * ["The eye (crust ?) laughs at the booger"?](https://japanese.stackexchange.com/q/36517/5010)

By the way, 抱き **合う** is "to embrace _each other_ ".
