Missing Pages

Today I was going through old journals just to refresh my memory and I found pages missing from around the time that I became a Somnambulist. When I...died. I can't remember what was written or if I'm the one who did it. There was no note explaining the missing pages which I feel I would have at least made note of it if I had done it.
 
So where did the missing pages go? I used to carry a journal around with me all the time then because I was so paranoid of losing memories that were important. Problem was that I thought everything was important. What if the missing pages WERE important?! I can't bear to bring myself to think that they were taken by someone else maliciously. Was there something that I need to remember that someone wants me to specifically forget? I tried reading the surrounding pages for some hints, but no memories were triggered. Why is this memory loss so random? GAH! Who would've done something like this? And why? I trust Lucius; I don't think it would've been him. Right? With me being away in the Drafted Service so much right now, I don't even know who all may or may not have had access to our home and belongings. I should talk with Lucius next time I'm home. He'll know what to do. I need to find out if there are any other missing pages, too.
