What’s worse: experience horrific pain with no memory of it afterwards, or experience no pain at all but have the false memory of having experience horrific pain? ——— Pain implies that your body is somehow being physically damaged. The former sounds better, but taking that implication into account, it's actually worse. Important to note that bad false memories can also be considered some sort of damage, but of a mental nature. So I consider your question as a trade-off between physical and mental damage.
