That filter is not affected in puberty afaik. What happens in late adolescense is the frontal lobes developing (the last stage in brain development). The frontal lobe is the place where self-reflection and ethic/moral stuff happens. That's why it's usually a troublesome time.
That filter can be temporarily weakened or completely turned off, wich can be quite a pleasant experience ;)
Imho, the brain is capable of generating a lot of data, and doesn't need much input for it (at least not immediate input).. In lucid dreams, things can become very real and detailed, eben more detailed than in awake state, where the brain drwas from life experience and memory.
