My most hilarious FA was to "wake up from a lucid dream" all excited, then go to the room and meet my dad and uncle (who lives in another country). They were dragging this mattress and I just sat there looking at them. When my father asked me if I was going to join them for lunch at my grandmothers house, I told him I couldn't, I had to write down my fresh lucid dream. I went to my room, a bit too dark, grabbed my DJ...and noticed something was wrong lol. "why would I leave the room without writing my lucid down?". And then I woke up xD

I'm gonna approach this in a different perspective (sorry Fogelbise!), and state that I'm a huge collector of dreaming memes. And what I caught up is the number of ordinary people (non-lucid dreamers) that exposes the super common situation of experiencing an FA in week days. I'd go as far and actually hypothesize that false awakenings could be a "desync" of the two mechanics: homeostatis and circadian clock.

There's a study that I've been trying to find for a bit that relates to this post. Point is, it would make all sense: you start building adrenocorticotropin at a faster/earlier rate than expected because of X event (school/work), but since your body is still locked on a sleep trance, your brain would "counter" this by providing you with a false awakening. A bit of a crazy theory, but it would explain why we see so many reports of false awakenings before important/stressful days (can't be late for school, got a meeting tomorrow), or in our case, I'm about to become lucid! You may think lucidity and waking life are different concepts here, but I'd say the brain interprets lucidity as it is: a step up closer to wakefulness, so it would make sense that your brain would try to prevent you from going lucid, because it really seems like you're waking up.

There's a technique in the book of Daniel Love (had the book in my hand today, need to check) that according to his reports, consists on stressing yourself with alarms to wake up in a false awakening. This is the inventor of the CAT technique, so I'd say it looks a pretty reliable method, and once again, this way of inducing fa's coincides with the reports people make.
