This is because dreams combine real content with negation. Negation means that there is an impossible situation. There can't be one between yourself and your boyfriend. To be clear, this person may have an impossible position. What appears here is that the position is consistent with reality, but it is impossible. People can't refer to people who can't be liked.
The abnormal situation in the dream is the main way to test the water bottle of the dream interpreter. The dream interpreter doesn't need to know what's going on, just need to know the meaning. We can guarantee that the meaning is correct and practical, and it will be proved right at once.
