Time Fractals

I'm having trouble with the idea that 'time' is organized into discreet 'streams' – binary branching of decisions great and small. That's not quite how decisions work.

If I decide to move across the room at a certain time, there's a million different ways I could do it. Each movement of each muscle could happen within a large range of speed, strength and direction. Every position puts me in a different place in the room, with a different vantage point. Anything I see could influence what I do next – do I see a good book I haven't read in a while? A movie I want to share with someone?

Any of those decisions could have a range of options and consequences. Do I read the book all at once, or break it up into any number of chunks? Where do I read it? What do I miss by doing that, and not something else?

I think it makes sense that 'time' is more of an evolving fractal. Leaves on a tree more than the branches. Certain actions might influence the shape of the leaf, and from there, future shape possibilities. Similar actions producing results that are nearly indistinguishable from a certain viewpoint, but, like the walking example above, might encourage some 'nubs' and 'prune' others – having a greater or lesser effect on future configurations.

Going back in time would be like running through a pile of leaves. Everything goes everywhere. You'd never go back to 'your' 'timeline' because you've influenced the fractal pattern in a billion different ways, even just by standing around doing nothing.
