That said I'm mostly Ne, but have a high developped Ni too according to tests. As far as tests can test it.
Anyhow, with people I know really well, family members, best friends, etc. I often know exactly what they think or how they respond to certain happenings and events. And have been known to pre-emptive strike at them with answers before they actually say the question. When this comes abruptly enough and cuts a new subject of conversation. It usually comes across as them believing I can read their thoughts.
But I just experience it as knowing how the people around me respond and recognizing it swiftly and with great ease.
You may call it psychic, I won't argue with you about that, but I experience it quite differently.
