Voltaj - Stiu

Here's another one. What does the first line mean?

Stiu - I know

Stiu ca-n noaptea mea cand totul e-n zadar
What the heck does this mean???
Stergi norii de pe cer si stelele apar!
You wipe away the clouds from the sky and stars appear
Stiu ca n-am simtit cand mi-ai luat inima
I know that you didn’t feel when you took my heart
Si stiu ca orice-ar fi, ea va ramane a ta!
And I know that wherever it might be, it will remain yours
Stiu ca de jos tu ma ridici cand imi zambesti.
I know that lift me up from the ground when you smile at me
Stiu tot ce simti fara sa-mi zici, si ca tu esti
I know all that you feel without you telling me, and that you are
Intr-o lume singura...
Alone in the world [?]

Refren:
In orice colt de lume-as fi
In whatever corner of the world I might be
Inima mea iti va sopti
My heart will whisper to you
"Te iubesc", "I love you", "Te quiero", "Je t'aime", stii...
I love you, Ilove you, I love you, I love you, you know…
In orice colt de lume-ai fi
In whatever corner of the world you might be
Inima mea te va gasi
My heart will find you
"Te iubesc", "I love you", "Te quiero", "Je t'aime", stii...
I love you, Ilove you, I love you, I love you, you know…

Stiu ca n-ai sa adormi fara sa'ti spun povesti.
I know that you won’t go to sleep without me telling you stories
Stiu ca ai sa ma saruti atunci cand te trezesti!
I know that you’re going to smile at me then when you wake
Stiu ca te bucurai de primul fulg de nea...
I know that you are filled with joy from the first flake of snow
Si stiu ca tu vei fi mereu dragostea mea!
And I know that you will be forever my love
