It translates to 'indifferent heart and emotion with cold dreams', suggesting someone emotionally numb, distant, unfeeling and detached from everything. And it could further describe an indifferent, unaffectionate hate. It seems the user has endured too much pain and thus chosen to remain cool and calm.
