There was a dream Long time ago

[sympathy]

There was a dream
Long time ago
There was a dream
Destined to grow

Hacerse pasion
Con fuego abrazar
El deseo de dar sin fin
El deseo de ganar

For the lifetime
Of progress
That runs here today
Will go all the way

Hey They feels like we've having
The time of our lives
Let's light the fire, find the pain
Let's come together as one inside
'Cause it feels like we've having
The time of our lives
We'll find the glory
All that we are, for all that we are
For the time of our lives

Hoy es el dia
Es la ocasion de triunfar
Para hacer realidad el destino que soñabamos conseguir
Una vida de lucha nos trajo hasta aqui
Y llegare hasta el final (Heaven knows...)

’Cause it feels like we’ve having the time of our lives
Juntos, unidos, triunfara nuestro deseo de ser el major
’Cause it feels like we’ve having the time of our lives
Juanto la gloria, junto a mi,
La hora llego de la verdad
El momento llego

Y ya nunca jamas lo podre olvidar...

'Cause it feels like we’ve having ('cause it feels...like we're having...)
The time of our lives
Juntos, unidos, triunfara (juntos, unidos, triunfara...)
Nuestro deseo de ser el mejor
’Cause it feels like we’ve having ('cause it feels...like we're having...)
The time of our lives
Junto a la gloria, junto a mi,
La hora llego
El momento llego (Oh!...)

We'll find the glory (Find the glory...)
We'll be there (In the end...)
For all that we are
For everything that we wanna be and all that we are
For the time of our lives
For the time of our lives...
Oh...

Can you explain the highlighted paragraph for me, especially the "Will go all the way"? Thanks.

I think that someone is recalling his or her progress of life in the past ("that runs here today") and the memory "runs into his or her mind". But what about "go all the way"?

[Tdol]

The progress will continue into the future and reach the maximum level possible. (I think)

[sympathy]

And what does "Let's come together as one inside" mean?

[Tdol]

Let's be so close that we have the same feelings. (again, I think- it's about unity, but I think 'inside' refers to feeling, thoughts, etc, as I can't see any reference for the word)
