Higher dimensions

I skipped two classes where lecturer explained fourth dimension and fifth dimensional vectors. Am I fucked?

They're just vectors with more tuples, what's the BFD?

Fourth dimension is duration, where your entire 3D space is moving through time in both directions. Someone looking at this from the outside will see you from the moment of conception to the moment of death in sequenced, lined up cubes.
Fifth dimension takes your life path and connects them based on points of divergence. So you have an infinite number of these 4D life durations branching off of one another to show different life paths based on the decisions you made and their consequences. Like right now, another fourth dimensional life possibility just branched off of the one I am in right in the fifth dimensional space because I typed the word "mountain" instead of "dew" first. The branched one is a reality where I wrote "dew" before "mountain." All of the possibilities of your life, the paths that you could take, exist in the fifth dimension.
I'm obviously not an expert, I'm just trying to make sense of how I've been learning the differences in dimensions the past few days.

Sorry to tell you, but this is most likely misinfo. Even if the 4th SPATIAL dimension had unique time aspects, like 4D beings being able to fast forward, rewind, etc, the 4th Spatial Dimension is just that, an extra dimension of space. You and OP should look into the concept of The Bulk, or Bulk Space. It's Higher Dimensional Space (4D or higher) in which our own 3D reality is embedded within, or nested, like how our visual field's are 2D planes nested within 3D space.

Don't worry, you'll catch up when they go over sixth and seventh dimension. Be careful though, eighth dimension is where shit gets complicated so don't miss that.

In what context are you using them? It's not particular hard for basic operations as its the same leap from 2d to 3d, just add 1 to the relevent indices

I'm not trying to be confrontational, but how did I contradict that by what I said?

It does work for 4d at least.
