I'm not sure I can do anything about the dizziness, but Rúmil mentioned that you have some fuzzed-out memories? I might be able to help there, although it would involve looking at them myself. I'm professionally forbidden to tell anyone anything about stuff I see in people's heads without permission, though.
Maybe. It depends on what happened to your memories; I couldn't address all possible causes of them being missing.
How kind of the trees. Plop. Okay, can you concentrate on a time that you're having trouble remembering, so I can go find it? And confirm that it's okay if I see the things that I'm sharpening?
I promise to be very nonjudgmental and not to gossip, anyway, Bella says, and she goes looking. What manner of fuzz is this.
This is not the right question; that is like asking what kinds of grass she is familiar with an able to distinguish when the question is 'has it gone to seed' or 'can she braid it'. She combs through the fuzz, seeing how it responds to subtle perturbations. Is it a separate thing or a property of the memories themselves? How deeply entangled?
That. Looks deliberate.
But if it's clumsy maybe she can just geeeeently sweep it away -
Well, she'll get faster with practice. She's not going to attack the fuzz with a snowshovel until she's worked with it a little more, there's delicate mind structures everywhere.
