Staring at/into the sun

[mafto]

Hello,
I've encountered the phrase 'stare at the sun', 'staring into the sun' several times in songs and apart from the literal meaning of it (which, however, doesn't always make much sense in the lyrics) I think I don't get it.
What could it mean?
Two examples:
And if I don't speak
It's cause I get disconnected
But I won't be burned by the reflection
Of the fire in your eyes
As you're staring at the sun

and


I see the way the salesmen
Stare into the sun
I stood and watched them
As they fell off one by one

thank you :)

The two usages of "Staring into the sun" that you've given don't point to any English idiom that I know of.
Song lyrics are generally just bad poetry. Does it really matter if you can't make sense out of it? What ever happened to listening to stuff like Bob Dylan and enjoying it even though nothing made sense?
