answer:It’s not possible. What might be going on, then? It seems to me there are two main possibilities: either he guessed that you had dreamed about him and wanted to probe for information, or he is sincere but delusional. In both cases, the “fact” that he “remembers” more than you do is a key clue. Things he remembers that you do not are in fact inconsistencies in your two experiences. They are evidence that you were not in the same dream. But the two of you are spinning them as experiences that only one of you remembers. (This is how folie à deux and related phenomena begin.) Maybe you both had explicit dreams about each other on the same night. That’s not strange at all, and is in fact more likely given how close the two of you are. It’s still just a coincidence, though. And if you are both capable of lucid dreaming, then it would be even easier to convince yourselves that you are capable of sharing dreams. Lucid dreamers are able to exert a certain amount of control over their dream environment; so if they dream about themselves willfully entering someone else’s dreams, it will feel more like they really did manage to do so. Furthermore, lucid dreaming inhibits the natural reaction to recognize the implausibility and incongruity of one’s dreams upon waking by forcing the dreamer to remain within certain rational parameters while still asleep. Thus it can be harder for a lucid dreamer to distinguish between fantasy and reality—despite the fact that a key feature of lucid dreaming is knowing that you are asleep and dreaming. For your sake, I hope your special someone is sincere but delusional. If it’s the first option, then he seems a bit manipulative. Then again, maybe he feels the same way about you that you feel about him, suspects that the feeling is mutual, and is just trying to confirm that before going any further. That would still be a bit dishonest of him, but maybe more forgivable. If nothing comes of this, however, he might just be looking for an ego boost.
