As I was going to sleep, I see two different light beams going through my window, iluminating two different spots of my bedroom but yet both going through my window at the same time constantly, how does that work? Are they in the same place at the same time? Or are they so fast that I can’t notice they are actually taking turns to come in?

I’m not exactly sure what you’re asking, but I hope this helps. The two beams are two completely different streams of light (photons/”light particles” or electromagnetic waves) coming in at the same time. It’s like how there is always water coming out of the multiple holes in a showerhead. There are countless individual photons that make up each beam. They don’t need to take turns coming through one hole after another. In fact, unless you have a completely opaque curtain or set of blinds, some photons are still coming through it and flooding your room with light; a lot of it is just blocked out.
