In that framework something most still be moving through an external time to be experiencing individual parts of it sequentially.

Here's a thought experiment, similar to the one-electron universe thought experiment: there exists one particle, the "consciousness particle," which randomly jumps around throughout 4D space. Whenever it appears at a 4D position, consciousness is experienced as computed by integrated information theory (or a similar model) [1].

When you experience a moment of consciousness at a specific 4D position, you experience all the memories of the "past" that are in your brain. Thus, the consciousness particle interpretation of consciousness is compatible with your direct perception of living a 3D life along a time dimension.

So basically we're all the same person we just think we're different people.

You still need real time for this. Without real time that particle can't move.

What do you mean by experiencing sequentially?

He means We (you, me, other humans) experience time passing consciously and sequentially.

We are on the inside of a 4 dimensional bulk. We are traveling through the temporal dimension.

As opposed to outside of it looking in. In which case we would "see" past, present, and future simultaneously.

Better yet, if we're traveling through that temporal dimension there must be real time. Otherwise how would we be traveling?
