I don't know if I'm going crazy or what...I think I've experienced another time slip! I have to start chronicling these moments. Maybe someone else has had similar experiences, I dunno.
Last night, I was super exhausted. I tried to go to bed early, but my mind wouldn't shut down because I'm stressed about work. I think I finally dozed off around 11:30pm. I have to get up in the morning at 4am, but I wake up frequently at night, so it's not even a full 4 1/2 hours of sleep. I distinctly remember walking to my kitchen to check the time, one time I woke up, and it was 4:22am. The next time I woke up, my stove said it was 2:07am. And when I woke up, I felt fully rested, like I haven't felt in a really long time.

This isn't the first time I've experienced this...it's happened several times, with the first being while I was going to college and tending to my newborn son a few years back. I was in a similar state of sleep deprivation, which was entirely restored. In the same way, I woke up, saw that it was nearly time to wake up, went back to bed, woke up again, thinking it was time to get up but finding it was much EARLIER than before, and then feeling fully rested when my alarm went off. And similarly, I only would have gotten little more than 4 hours of sleep that night.

I dunno. Maybe I am crazy. Maybe I just dreamed it and happened to just sleep better than normal. But usually, I KNOW the difference between my house in a dream (which is always contorted or somehow discombobulated) and my house when I'm awake. (Not to mention it's typically impossible for me to read anything in my dreams.)

It's strange...just a peculiar experience that seems to keep happening. You'll probably think I'm crazy. As someone who rationalizes everything, I feel like I'm going crazy, so it may well be a fair assessment. But I just want to get it out there, in case anyone else feels a little crazy, too.
There's nothing supernatural or even spectacular about it, just your mind wearing thin from too little sleep.
Sleep deprivation like that can cause small hallucinations and very lucid life-like dreams, which is why not sleeping for multiple days can make you go insane. Your time slips could be small waking hallucinations, or just really lucid dreams. You should get at least 6 hours of sleep most nights, and never pull multiple nights with fewer than 6 hours of sleep in a row.
