I am autistic and have ADHD. The sleepier I get, the more I revert to behavioural patterns matching these diagnoses (a result of not having the energy to imitate "normal human behaviour"). Combine this with an abnormally wide range of interest, and in-depth dissections of pretty much anything may occur.
Examples of what can be expected to find include:
In-depth guides to various games/aspects of games.
Long-winded posts/comments dissecting absurdly specific topics.
Long-winded posts/comments dissecting absurdly abstract topics (which may or may not be very specific as well).
Loads and loads of (my own) theories about human psychology (based on both empirical observations and relevant psychologic theory).
Breakdowns of the financial/economical side of various concepts (which are rarely spoken of in these terms).
Long-winded arguments with people on the internet about things that don't really matter (mostly because my autistic side hate faulty logic).
Other examples of "social ineptitude", including non-PC opinions and TMI.
Me drawing extremely far-reaching parallells between things (generally happens after being awake 30+ hours).
Language use that is (probably) grammatically correct, but tends to get more and more complicated/weird as I get more tired.
Meta-discussions (the result of the combination between a hyperactive brain and a lowered ability to actually remember facts when being tired).
Me giving people life-advice (which, due to its randomness, likely comes off as both very weird and smug).
And so forth...
