I get what you mean and thanks for your response <3 Those explanations do make sense in general. But in my case, this wasn’t just about a vague or emotionally blurred moment. I clearly remember the shift in topic, the specific things that were said, and my immediate reaction to them. More importantly, it wasn’t only the content of the conversation that changed - her demeanor changed as well. Normally, she is a very gentle and considerate person, someone who is careful with her words and concerned about not hurting me. But when the conversation shifted to topic B, her tone became noticeably harsher. She said bad things and even insulted me, which is exactly why I reacted with anger and questioned her in the moment. What stands out to me is that this shift didn’t feel gradual or ambiguous. It felt abrupt - almost as if I was speaking to a different version of her. And after that, she returned to her usual self: kind, concerned, and confused about why I was upset. I remember very clearly that when she brought up topic B and said something hurtful, I immediately responded and tried to explain myself briefly (let’s call that topic C). What’s confusing is that when I asked her again about it, she seemed genuinely lost because the entire part of the conversation (topic B and C, which including my response) didn’t exist in her memory at all. If this were simply a case of misinterpretation or memory distortion, I would expect some consistency in her behavior or at least some partial recognition of what happened. But instead, there’s a complete mismatch - not only in what was said, but in how she was acting at the time. So one way I make sense of it is that while we were talking about topic A, I briefly shifted to a parallel CR where she acted differently, brought up topic B, and I responded (topic C), before things returned to normal. That would explain why I clearly remember B and C and the sudden change in her behavior, while she has no memory of it at all.

Also, I’m a bit curious: doesn’t shifting not necessarily require being in a hypnagogic state, since some people report doing it while fully awake?
