Is it normal to maintain an incomprehensible diary?
I've maintained a record of my introspective perceptions through regular journal entries. The reason is so that I may better understand, interpret, and track my mental progress over the years.
At least once a month, I'll take a few hours out of an evening to write down whatever thoughts come to mind. I am to write these thoughts directly and to the core. The only problem is, I've found the resulting entries have gradually become less comprehensible with time. The words themselves are very clean and legibly written; that's not the issue. My trouble is, I've noticed a decline in the functionality of such written thoughts. More broken sentence structure, nonsensical words, and complicated codes have been appearing in my entries since the start of the record. Normal word usage fails, and soon I observe myself describing my own mental processes using mismatched vocabulary, such as "those half-asleep injuries".
Nowadays, I hardly understand my entries at all. It's as though the longer the entry, the more chance it has to become this way. I've maintained this archive of thoughts, this diary, for a number of years now. Although my current situation may or may not sound insane to outside ears, I should make a point for good measure: My ability to function in the social world is just fine, don't worry. But as far as the general act of keeping a diary/journal/mental record goes, is it normal to maintain an incomprehensible diary?
