Survey conditions
Each time you enter the dream, the maximum duration is six minutes. Interactions in dreams consume time; you need to unlock the Mental Lock to obtain hidden clues, which may also alter the story route.
Six minutes with the heart lock
Each time you enter the dream, it lasts six minutes. The target's Mental Lock blocks access to deep memory, requiring investigators to try different actions to open the barrier; Dreams follow their own rules, rather than the usual laws of physical reality.
