Somehow the chorus of this song reached into me once, and to me, it is interpreted this way:
When there is mistrust,
(Even the best fall down sometimes)
you will find faults even in a flawless thing,
(Even the wrong words seem to rhyme)
and all the negative stuffs will be anchored in your heart deep,
and you remember these melancholy memories vividly instead of the merry memories.
(Out of the doubt that fills my mind, I somehow find you and I collide.)
and then I'll find out that of all the doubts I have on - your reasons for doing certain things,
I'm sure that you and I collide...
(Even the best fall down sometimes)
repeat
(Even the stars refuse to shine)
Our qualities fails to be recognized since we have so much misunderstandings
(Out of the back you fall in time, somehow find you and I collide)
A lil weird, but I think it means out of all the times i recall our past (conflicts), I'm sure you and I collide.
These few lines struck me hard that day, and so this is my interpretation for just this part, thus this might not be correct but it's personal.
