But I don't really think that going to bed at odd times and sleeping late is a spectrum thing. I could be wrong. I really think such patterns are due more to anxiety and depression, i.e. the secondary symptoms of Aspergers.
I think it can just be a matter of personal preference, plain and simple. Also the need for solitude, which is easier to indulge in at nighttime.
There could be a genetic factor...actually, I think I read an article about that awhile back but I don't remember now. Almost everyone on my mother's side of the family seems to be hardwired to sleep late and stay up late. We all revert to the same sleep cycles when we are not following any work schedules.
I need about 8-10 hours of sleep every night to feel rested, but I don't always get that much. I can function on a lot less but it catches up with me pretty quick.
