it is a fair assumption
they have their own form and looks of course, but it requires understanding how things move in dimensions really
from there you can only interpret, as you do not have to physical hardware and subconscious to perceive it.
Like say an aspect that moves, (only) it flutters through space, we can see as movement, and then the colour will depend on the light refracted, etc and this is what we think we may have seen, as it fits within the internal library of what is possible.
But perhaps it was something or an aspect that just existed as movement only.
I only offer abstract reasoning to provide insight hopefully.
So, you ‘interpret’ through your interpretation hardware ‘your world view’
things you believe possible and within the limits of your wiring.
