My brain kept wondering whether the alarm would go off.
Similar stuff has happened to me (not with sunrise alarms, though—never tried one). The solution is setting a loud, reliable, ‘back-up’ alarm at the latest time at which you could possibly get up in time.
I’ve also discovered an alternate solution: try challenging yourself to wake up before the alarm goes off. Works even better if you tricked yourself into thinking the alarm was ever actually turned on.
