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?
You might want to look at The 5 Aggregates, namely the aggregate(s) of Perception, Mental Formations and Consciousness.

Especially the forth aggregate of mental formations relates to what you are describing, since it contains volition (cetana). See also SN 12.38: Cetana Sutta.

The Abhidhamma goes into further detail on the topic of Citta &amp; Cetasikas.
Ven. Bhikkhu Bodhi has written an execellent summary called "The Abhidhammattha Sangaha - A Comprehensive Manual of Abhidhamma".
