Subjective means shaped by personal feeling rather than fact. A subjective judgement, purely subjective, subjective experience.
It is set against objective, and the pair does a great deal of work in argument — often more than it can carry, since many judgements are neither purely one nor the other. In philosophy, subjective experience means what something is like from the inside, which is the hard problem of consciousness. Note subjectivity; and that in grammar the subjective case is another matter entirely.
