How's this analogy for sensory overload?

I've been thinking about this for a couple of days, and wonder if anyone else relates to this? Apologies if this is obvious or a well known thing, it's new to me.

So the analogy goes that my senses have a buffer. As in, light comes in to my eyes, then it goes to the buffer, and at some rate the buffer empties. Normally, this is fine. Like in a calm, nice environment the visual information goes into the buffer at about the rate the buffer empties. But some environments require more visual information to process, and therefore take up more room in the buffer. So a bright, busy environment takes up more space in the buffer, therefore it fills up the buffer faster than it can empty, so the buffer overruns and you run into whatever issues that might cause for you.

Alternatively, think about it as a bath with a drain that empties at a set rate. Certain sights/sounds/smells/etc need a larger amount of water to process than others. Therefore, difficult environments for us cause the bath to fill too fast and eventually overflow.

Of course, the rates at which things are added to the buffer/bath, and how quickly it empties, and what the result is when it overflows is different from person to person. I actually started thinking about this in relation to why I get ocular migraines, and then I realised that this analogy can be applied to any sensory overload situation.

The reason I think this is helpful over just saying 'sensory overload' is because it paints a more complete picture, it helps others understand that different types of the same stimuli affect us differently, it also helps others understand why time out in a calm or appropriately stimulating environment helps us, and generally helps explain why we get overstimulated. Including the fact that you might get overstimulated (buffer overflow) from a fairly ordinary situation that normally would be fine for us, if we'd previously in the day been exposed to something that fills the buffer up fast and haven't had time to let it empty.

Anyway, anyone relate to this? Or have I just come up with a more elaborate way of saying 'sensory overload'?
