So this happened to me today.

After spending the whole night coding / watching Netflix I was sitting in my chair and looking at my screen with VSCode (dark theme of course) open. It was pretty dark in my room because the only source of light was my computer screen, which was still pretty dark because of the dark theme.

So, while looking at my code I suddenly noticed that the room had gotten a bit brighter. I wondered wtf was going on.
I looked out the window and saw that the sun was rising. Then I looked at the clock:
5:30 am.

Me: 'oh, lol'
