One Direction - Once in a Lifetime Lyrics Meaning

This song is about falling in love, and losing that person you love. Let's go more in depth: The first bit goes: Once in a lifetime,It's just right, We make no mistakes,Not even a landslide, or riptide, could take it all away". The singer describes the perfect love experience, that only comes once in your life. Once in a lifetime, a love occurs in which no mistakes are made and landslides and ripstides have no effect on whatsoever. The singer is obviosly very distressed, and the next bit will speak from the point of view that they've just ended their relationship."Somehow
it feels like nothing has changed, Right now,
my heart is beating the same, out loud, someone's calling my name, It sounds like you". The singer is in a very strange place and is feeling almost paralyzed, frozen, immobilized and powerless, as they're heart continues to beat the same rhythym. Distantly, their lover can be heard calling their name. The next part is:"When I close my eyes, All the stars align, And you are by my side,You are by my side". While the love so perfect that it only occurs once in a lifetime is to r n from them, they lay there and close their eyes and see everything perfect and how it used to be, with the lover by their side."Once in a lifetime, It's just right,We are always safe". At a point in their relationship, they were indestructable."Not even the bad guys, in the dark night, Could take it all away". The singer reminsces on their once perfect, once in a lifetime relationship before an extremely strong occurences caused the once titanium couple to fall to pieces. "Once in a lifetime
you were mine."
