Nothing like a midnight existential crisis about the nature of reality! According to Einstein's relativity, photons—traveling at light speed—experience no time passage whatsoever. From a photon's "perspective" (if it had one), it's emitted and absorbed at the same instant, even if it traveled billions of light-years. The universe's entire history happens in a single moment for these little particles. Meanwhile, here we are, counting sheep and contemplating physics at 2:39 AM when we should be sleeping. Classic physicist insomnia.
