ETA: (totally got an old phrase wrong) Sometimes sparks are just sparks and they just fizzle away. (Ever watched old TV shows and see how lame they look?) But having said that, yes, sometimes sparks are indictive of more. The question is..how will we know?
I'm not sure.
But I can tell you that starting today (Thursday 10/1 2:00am EDT) Mercury will sextile Mars and that is a spark on a spark. If you get a bee in your bonnet to do something--it will probably be an important move for action. And you may have a follow thru on the weekend. Why? Well, at first glance this might not seem like much of an aspect but what catches my eye is that this aspect repeats on Sunday 10/04 7:37am EDT).
Additionally on Sunday Mercury will oppose Uranus. This is a wildly chaotic and nervous energy. And that it is happening on a FULL MOON (see later post) we will all feel like a cat on a hot tin roof. Running all over, trying to get somewhere but not sure where or why. But somewhere in that mad and cuckoo energy there could be a road to change (uranus). It might not make sense and you might not even think you need the change (opposition) but you could find yourself right on the first step to change.
Watch and see what roads appear in front of you for the next few days. You could be surprised. Follow the sparks.
