Mentioning lack of dreams is on point. As a student I would do at least 1-2 all nighters (~36+ hours without sleep) a week. In the rest of the week I would probably be partying. In hindsight, it was pretty stupid as I was incredibly inefficient at everything, my health was poor and I was cognizant that my mood would get depressive the more sleep deprived I got. One of my benchmarks of my tiredness, and conversely how rested I was, was if I was having dreams. When I was exhausted, sleep would be pure black abyss and the time between sleep and awakening could have been the blink of an eye for all I knew. When I was sleeping reasonably (~6.5+ hours) I would start to dream again after a few days. I take things a bit easier now, it's much easier to resist distractions like Facebook or the news when I'm rested than when I'm extremely exhausted. Heavens knows what happens during parenthood and you simply have no choice, presumably there must be some psychological instinct that takes over...
