it may help if you were to think of yourself as similar to a multi-faceted gem.
while your conscious mind facet is busy looking in one direction, you have
other portions of yourself looking at other things. the "work" done by your
HS might occur at any time; perhaps completely independent from conscious
cues. for you to
want to provide aid to your dad is a more significant signal
to your HS (in my estimation), since it is heart directed.
for your conscious mind (while in a sleep state) to be directed to your mom is
suggesting to me that that is the area you might achieve the greatest results
through applying conscious efforts in easing tensions. [since everything is
connected.]
perhaps your conscious mind can release judgments held against your mom,
specifically through that "does need to be spoken about" incident/circumstance.
'raise your vibration' to match that of your HS in order to commune and discover
what efforts have been made on your behalf, and to the welfare of all concerned.
