Notice when multiple individuals enter your life and reveal something in common, its telling you to tune into intuition, pay closer attention to something and act. It synchronicity. We cannot see synchronicity, but we can see the consequence of it. That it, synchronicity draws attention to things we do not initially recognize.Similarly, as stages of awakenings occur within, you cannot tell exactly what has happened to yourself but see the consequence of it in how you think and feel. Something mysterious is happening. The more you feel it, the more awareness expands, the more you start to grow aware something inside you will start responding to it. This is the activation of subtle senses that tune into energy.
In another way, what has happened in you can trigger unfolding processes in others. Your synchronicity cannot be the cause of my synchronicity. Yet, your awakenings can preciptate the 'ah-ha' processes of others. My awakenings can energetically reverberrate in ways that prompt others to see differently. That is, if something has happened somewhere and we become available to it, we remain vulnerable to it, something can start responding in us that is parallel to it.
So, if someone plays music that inspires you to dance, the urge to dance is not caused by the music. Its a parallel urge within you. Something dormant, the energetic urge to dance, is provoked, inspired. If it is a cause, then everyone would dance to the same music. That would be hypnotic trance of the Pied Piper.
