Most of the things that happen in the dream are not true, because most of the things in the dream are due to the impression of the outside world deep in your mind, or your subconscious impression. Then I brought a light, or some plots you saw through some media, TV, etc. This also forms an impression in your mind, which appears in your dream. This is the meeting of love and love, or some scenes you usually imagine yourself, which will also appear in your dreams. Most of the scenes in the dream are not true, but occasionally he will overlap with some scenes in reality. You think he is real at this time, but it's just a coincidence.
