You are stepping beyond the border beyond which dualistic thinking makes no more sense. There is a reason why light often is referred to as having a dual nature, being a wave (no particle) and radiation (particle, photon) - you can prove both natures by choosing an according experimental design, it has been done, and repeatedly, so its confirmed. It's crazy, but we have to live with it.
Also mind you that on quantum levels, "particles" no longer are or could be understood as existing entities of something or that quantums are materialistic quantums. A quantum is a certain ammount of something. The term to point out here is "tendency". Meaning the tendency for existing for a given timeframe, or not. Also, "probability clouds". Particles not necessarily exist for sure, but have a tendency to exist only in a given point of space and time. And a quantum also could be described as a (varying!) ammount of tendency for something to exist for a varying ammount of time.
Quiz time: what is that "something"?
It's all crazy down there in the quantums.
Physicists sometimes say those claiming they have understood quantum physics by that give proof that they have not understood it. You "can not" understand it, not in the way you understand ordinary life in the ordinary world. And even that ordinary life often does not make sense, does it.
What it all is, in the end? Space. Empty void. Both in the subatomic and the astronomic dimension. Talking metaphysics here, a screen maybe serving as a projection screen for movies of unlimited content and variation. Where nothing is certain and there are no limits, everything is possible: unlimited potential.
That you cannot describe aspects of these things without using the language of abstract mathematics already demonstrates that our ordinary everyday-concepts of thinking do not work well when approaching these things. Best thing would be to leave dualistic thinking and talking behind.
Which maybe implies to leave our humanness behind.
