It must be terrifying if you're a galactic entity and have experience, awareness, and consciousness, but no autonomy w.r.t. movement, trapped in a trillion-year path that you cannot escape.
(Apologies for the Socratic barrage, but this line of inquiry triggered my inner first-year philosophy student.)
Surely such an entity would not see itself being trapped at all, any more than a tree does. It is what it is.
On the contrary, it probably pities humans, asteroids, comets, moons, planets, and everything and anything else that is smaller, younger, with a shorter lifespan, or less energetic.
> Assuming that the galactic mind works in and through electromagnetic fields, then its thoughts and perceptions must be very slow indeed, by our standards. The radius of the Milky Way is about 50,000 light years, so it would take at least this length of time for the galactic centre to perceive what is happening at the periphery, and as long again for it to act on star systems at the edge.
Instead of having a consciousness that has to wait 50,000 years for some input, it makes more sense for a consciousness to experience time on a scale where input happen in (say) 100ms consciouss-perceived time or so. So what looks like 500,000 years for us is a second to a galaxy.

because your intellect would grasp the immense heaviness to realize you're mortal, that your ego will end.
