Перевод - Польский-Английский - To ja, Twój sen, twoje przeznaczenie.

I think here it's talking about destiny, right?

I wasn't sure which one (destiny or destination) I should choose. (Because 'przeznaczenie' can mean either of them.)

I have finally chosen 'destination' because I think the autor means that s/he is someone who will inevitably 'happen' to the addressee.

'Destiny' would suggest that the autor means s/he is the Fate.

What do you think?

Cheers,
Oles.

I think you may be right, it's a bit confusing when a noun has two meanings and we don't have a broader context which would give us the exact idea of what the writer meant.

I'll keep "destination" and wait for the poll. Perhaps our voters can help.
