I know I don’t have a sleep disorder, but I’d say I definitely have weird sleeping habits. These get worse when I have no sort of job to help regulate when I sleep and when I get up.
For example, if left on my own, my sleeping schedule tends to shift so that I go to bed between 5 AM and 6 AM and wake up around 10 AM.
I also think I’m pretty unusual when it comes to sleeping in general. I can go from awake to asleep in about three seconds, and it doesn’t matter if I’m lying down or sitting up. I’ll just go out. I feel like I go right into REM sleep, too, without any sort of buildup to it.
It would be interesting to go to a sleep lab or something and get my sleep patterns analyzed.
