Which Consciousness Causes Heartache in Dreams and Waking Life?

Which consciousness causes heartache both in and out of dreams? Someone dreamed that their car was crushed and completely vanished, feeling intense heartache in the dream. After waking up, the heartache persisted. Which heartache is this? Which mind's sensation is so persistent and unyielding? Waking up from heartache in a dream, waking up from fear, waking up from joy—why is it like this? Which consciousness's sensation is involved? Is the consciousness in the dream the same as the consciousness outside the dream?

Manas (the mental faculty) is a continuous consciousness, identical across past lives, present life, and both dream and waking states—it exists throughout. Manas governs falling asleep and waking up. Heartache experienced in a dream is the same as heartache experienced while awake; it must be the sensation of manas that causes the heartache. Moreover, manas can trigger changes in body and mind; it is manas that enables the heartache. When consciousness experiences heartache, it is very subtle, like a breeze brushing the sea surface, causing no ripples and provoking no bodily or mental reaction.

In a dream, manas, through the discrimination of isolated consciousness, mistakes the dream for reality, treating it as a truly existing realm. Consequently, it becomes deeply attached to the dream, to the point of agitating the body and mind and causing the phenomenon of heartache. After waking up, manas seems to remain immersed in the dream, deeply affected, causing the heart to still feel pain. Although the isolated consciousness of the dream has shifted, manas remains attached to the dream, compelling the isolated consciousness to recall the dream realm and experience its effects. Among these, the sensation of manas is deeply ingrained and difficult to change, while the sensation of consciousness is easily altered, readily influenced by encountered circumstances.

From this, it can be seen that the sensation of manas is not entirely neutral feeling (upekkhā). Otherwise, it would not cause such significant fluctuations in body and mind—it would not cause one to wake from pain, joy, or tears, nor would it be possible to continue crying, rejoicing, or feeling pain after waking up. Severing the view of self, severing sensations, severing perceptions—specifically, eradicating manas's view of self, sensations, and perceptions—is the most difficult task. All views, sensations, and perceptions of consciousness are easily addressed.
