What do you write about in your journal, and do you ever look back at it, and see a pattern as I do?

I write about everything going on within myself. Sometimes in a conversational way with myself to get answers or go deeper. Planing my dreams and feelings. What I am going to do, what I want to do…it is a stream of consciousness. I look back and not sure if there’s a pattern maybe only that I write alot more when I am in negative emotion
