The density of foreverness and violet ray

[Minyatur]

How does being a different experience cause them to not remember it? will they forget the current density totally once we enter the next octave as well?

Well if the nature of their densities is alike ours, you wouldn't be self-aware til the 3rd density, so much less in perception of all the infinity that leads to that moment. Technically you're the whole of it yet only the layer of us we call Intelligent Infinity truly has the whole view.

I think it works a bit like our veiling process, our Octave is veiled to others Octaves and this veiling can be pierced. I wouldn't doubt there are many souls who know more about the previous Octave than Ra.
