Before ascribing a personality to our subject perhaps we ought, first, to ask what is matter? If dark matter acts as if it were matter, does it follow that it must so be? Could be be talking about a proto-particle having the essence but not (all of?) the elements associated with matter as generally understood? Just a thought.

Could DE be "Hot Dark Matter", whilst 'DM' is "Cold Dark Matter" ? I.e. I understand computer simulations are run, with either CDM, or HDM; but what about both, in the same simulation ?? Perhaps 'DM' = CDM ("brown dwarves" ?); and 'DE' = HDM ("primordial neutrinos" ?).

No, matter - whether hot or cold - exerts attractive gravitation whereas DE works repulsive.
