Hmm. In general, regained memories are defined by their vividness - when you reclaim a memory they aren't vague inkling so much as something powerful that sticks out in your mind, with a freshness that is almost like completely re-experiencing it (except that it probably won't traumatize you as much as it did the first time if it's something really nasty.)

However, when regaining memories, characters won't necessary remember what they were THINKING the first time they went through it. So if everything in the scene was set up to look perfectly realistic, without particularly noting the cameras or the like, there's the possibility she could make the mistake. But you'd have to be careful with how you framed the memory, basically.

The key point is that regained memories are never going to be 'muddled' precisely.
