Thanks for sharing your experience! What you're doing seems like a turbo-charged version of the emotional integration work I do with expressive writing. I use writing to discover and investigate thoughts and feelings that I've repressed, i.e. things that are still in my subconscious mind but not in my conscious awareness. Unfortunately, after doing this for a few years, I have to wait until they start to show up a little bit through irritability and other uncomfortable feelings before I can start digging in and working on them. This device seems like a way to force those unresolved issues to come to the surface.
