Mental Sensation series tries to facilitate readers' immersion into the dream experience while providing a comprehensive presentation of the "spiritual journey." It achieves this by shaping a sense of unreality akin to that of a dream, discovering aesthetic fragments in the mundane aspects of daily life, and unleashing the aesthetic impulse when these fragments accumulate and reach a certain threshold. "Spiritual journey" is a state in which one transcends worldly appearances and gains true insight into oneself.
