孤独入客枕

This name implies being in solitude as deep as seeping into the guest's pillow, which vividly conveys a sense of lonesomeness and detachment from the mundane world. It shows that the owner might be having an experience or yearning for a state away from crowds, perhaps feeling isolated, yet there's also a tinge of self-indulgence in such loneliness, possibly reflecting introspection or poetic desolation.
