Adaptive brain function integrates sensory impressions with intrinsic brain activity. While dynamic brain state switches are well-characterized in resting states, their remodeling by naturalistic stimuli is poorly understood. This study shows that fMRI-measured brain state dynamics reshape from bistable transitions at rest to a sequence of well-defined states during movie viewing, temporally aligned to movie features. These brain states covary with physiological states and subjective engagement. Data-driven decoding reveals distinct reshaping of functional network expression and reliable state transitions accompanying the shift from rest to perceptual immersion.
