A Body Hard to Direct

A Body Hard to Direct
Preparing to act
Naoki Higashida says that even a simple task can require him to think through and picture each step before encouraging himself to begin. Wanting to act does not guarantee that his body will follow.
Estrangement
At times, his body feels as if it belongs to someone else. This sense of alienation helps explain why commands to move or remain still can feel like demands made of a faulty machine.
Limbs Without Clear Location

Limbs Without Clear Location
Uncertain movement
In gym class, Naoki Higashida does not always know where his arms and legs are or how to make them do what he intends. He compares his limbs to a mermaid's rubbery tail.
Practice and distance
Difficulty judging distance can make reaching for objects or copying movements hard. Repetition and practice may help, but the difficulty remains a matter of bodily perception rather than simple unwillingness.
The Body in Motion

The Body in Motion
Feeling present
Jumping lets Naoki Higashida feel his legs and hands more clearly. He also describes it as shaking loose the restraints that emotional intensity seems to place on his body.
Motion as relief
When stillness makes him feel trapped or detached, movement can bring a measure of calm. His account turns visible motion into a way of sensing himself and releasing pressure.
Sound as a Threat to Place

Sound as a Threat to Place
More than irritation
Certain sounds can make Naoki Higashida feel as though the ground is shaking and the landscape is approaching. The fear is not simply that a noise is unpleasant.
Restoring orientation
Cupping the ears helps protect him and recover a sense of where he is. He describes gradual familiarity as one possible route toward feeling safe, while emphasizing the importance of security during the experience.
Light and Relief

Light and Relief
Filtering brightness
Naoki Higashida describes moving his hands in front of his face as a way to soften direct light. Unfiltered brightness can feel sharp and painful to his eyes.
A comforting sensation
Light can also console him, so the movement is not simply avoidance. It changes how the light reaches him and creates a gentler sensory experience.
