What buddhist topics cover the arise of meaning?

I'm convinced that I give meaning to whatever I perceive. Which either can make me suffer or happy. So I have seen that I create my own suffering. That state is reflected in my body (or bodies?). Objective reality holds no meaning it itself. The meaning arises the moment I interpret information. This insight came to me after meditation where I saw things arising from nothing. I could choose to stay in the nothingness by not interpreting, or observe, interpret and meaning arose. What buddhist topics are related to this phenomenon?
