Speaking of personal associations (from previous post)

I've talked about the themes for the upcoming final project in my studio journal, along with a whole bunch of brainstorming. The main element will be the audio component, in which I compile an audio montage made from collected audio excerpts (from recordings I make myself, film, music, and other media) which will serve to communicate the theme to the viewer and hopefully also affect them in some way. Last semester I created an installation similar to this, but instead of being installed in a large space like the room I am planning on using this time, I built a human sized box to restrict movement and isolate the viewer from the outside world.
The themes for this semesters project were to be relating to social anxiety, and would incorporate primarily recordings of outdoor, social surroundings.
As the project unfolded, however, I found that the process of recording sounds of such a specific nature (I was looking for a lot of dialogue, specifically that which could feel potentially oppressive), and still having only a vague idea of what that 'specific nature' was, it would be difficult to pull together a project with those themes in the time I have. May be an idea for a longer term project.
Back to the theme of 'personal associations', and also memory.  I am very interested in all aspects of the human experience, especially psychological related ones, I think an idea that is explored in a book I've been reading, 'The Remembered Film', which talks about the unconscious associations a viewer makes from their experiences in life and from previous films could be something to explore as a theme.
       - Immediate external surroundings; subconscious associations provoking certain reactions and            emotions
This is something I'll be looking into more, but I think a majority of the recordings and other audio excerpts I've collected from the other project apply to this theme. The fact that the audio is quite abstract will help along the idea of the audience making each their own personal associations based on the things they've encountered throughout their life.
