Anyone who has slept next to someone they love knows what this song is about.

My Opinion

I like how everyone's trying to analyze this song so deeply when the answer is so obvious. This song, like fridaydan said, is about that pleasant moment where you've fallen asleep beside the person you love and you may wake up before them and just breathe them in, enjoying them.
