I don't mind helping, but...

Even I'll have trouble finding attachments she herself can't remember.

That may be true, but remember what you told me.

"Dowsing is a technique to bring subconscious information up into the conscious."

Even if she can't remember clearly, if it still remains deep in her heart...

If she uses dowsing, she might be able to find the subject of her attachment.

...That's certainly a possibility.

However, making her go dowsing herself...

With no experience, there's no way she could accurately detect anything.
