When staying awake for a long period (3 or 4 days), some weird phenomena can occur. In my experience, it was always triggered by thinking too deeply and has in other occasions too.

Do these things have names at all?

  • $\begingroup$ The brain is a complex dynamic system; if you perturb it outside of its normal functioning parameters (for some examples: severe brain damage, psychadelic drugs, sleep deprivation), odd behavior can result. Note that sleep deprivation for ~2+ weeks kills rats. The rest of your question is too much based on personal health and experience to be on-topic here at Biology.SE. $\endgroup$ – Bryan Krause Jul 21 '17 at 20:38
  • $\begingroup$ “Deprivity”? Oh, I see, very clever pun on “depravity” and “deprivation”! $\endgroup$ – DaG Jul 21 '17 at 20:47
  • $\begingroup$ @BryanKrause, I completely disagree. The question of whether there are formal names for the mental changes the OP experienced during sleep deprivation seems to be fine. $\endgroup$ – Michael_A Jul 21 '17 at 22:23
  • $\begingroup$ @Michael_A Tried to make the question actually about that to keep it on topic, and retracted my close vote. $\endgroup$ – Bryan Krause Jul 22 '17 at 1:14

    $\begingroup$ @BryanKrause, Nice. I thought the original description was a good attempt at describing the phenomena; it's a hard thing to describe. I agree that more words often make discerning the question harder. $\endgroup$ – Michael_A Jul 22 '17 at 7:04

During extreme sleep deprivation you can briefly fall asleep, this is known as a microsleep. The disorientation that you experienced can be referred to as Hypogogia.

Hypogogia covers a range of effects including visual and aural hallucinations as well as having thoughts that are experienced as seeming logical during the microsleep but illogical once you're awake.
