eating, within dreams, may be speaking of ideas which you are 'consuming'...
which will become metabolized, and form the basis of what composes you [the dreamer].
for you to be attending a lecture on twin flames is a clear indication of this idea
becoming incorporated into your being...
especially due to your enjoyment.
McDonald's is "fast food", so there's the idea that what you're ingesting isn't
nutritionally valuable, yet you weren't served through the take out window,
but were instead attending the restaurant, which provides a feeling of
something more 'substantive' to me. that location may be suggesting that
your meal is something readily available to virtually anyone wanting it.
the "separate tables" feature seems a clear indication of not having been
paired off just yet.
