1&3 didn't do anything for me

But 2 if you flip it horizontally is how I see the world after about a week and a half of no sleep. The orange in particular makes me think of tailights.

4 is soothing to me somehow. Just a general melancholy. A feeling that I've seen it before and it was good times that I won't experience again. It kind of reminds me of a Leonid Afremov painting of a park after its rained.
