It's not a superpower. For me it's a combination of two: Urgency and having had enough sleep. If I have a flight, I almost always wake up 30 minutes before my timer go off; even if I didn't get enough sleep. If I have nothing important to do the next day, my brain will usually ignore the waking up part and carries on. One thing I noticed is that in the last year I have been waking up just a few minutes before my alarm goes off. My postulation is the iPhone alarm sound. It's bizarrely painful that I think I'm waking up just before it to avoid hearing it.
