Is this a proper use of tara and toki for "when"?


Consider:

>   1. 気がつい **たら** 皆さんは寝ていた。
>
>   2. 気がついた **とき** 皆さんは寝ていた。
>
>

My English interpretation: **When** I woke up (came to), everyone was
sleeping.

Is "when" enough to capture the nuances of the Japanese sentences? How are
`たら` and `とき` interpreted differently in English?




I think I'd need more context, or at least I'd need to know if you want it in
spoken or written style..., but anyway I'd rather say  
'[気]{き}づいたら、みんな[寝]{ね}ていた' (kizuitara, minna nete ita.)'  
'[気]{き}づくとみんな[寝]{ね}ていた' (kizuku to minna nete ita.)  
'[気]{き}が[付]{つ}いたら、みんな寝ていた' (ki ga tsuita ra, minna nete ita.)  
'気が付くとみんな寝ていた' (kiga tsuku to minna nete ita.)  
because 「[気]{き}づく」also means 'to regain consciousness'=('to come to', no?). We
often use the verb [気]{き}がつく/気づく to mean 'to wake up' in daily conversation,
like 「[今朝]{けさ}、[二度寝]{にどね}してさ～、で、[気]{き}が[付]{つ}いたら８[時]{じ}だったのよ！」or something
like that. Of course you can also use the verb '[目]{め}が[覚]{さ}める' instead.  
  
If I were to put any particle after みんな, I'd rather use は, and I wouldn't say
みなさん here because you're not talking to 'everyone'.  
  
If you want to use とき, I think '気が付いたときには、みんな寝ていた' would be more natural,
though it might sound more like 'Everyone had gone to sleep by the time I woke
up/became conscious.'  
  
Just one more thing... I think you can also use the verb '[眠]{ねむ}る' instead of
'寝る', like '気づいたらみんな[眠]{ねむ}っていた' etc.
