I haven't read anything other than the first post so sorry if this is redundant.
Your theory about decision and stuff feels completely correct to me. I am on autopilot 24/7 and its bad for me but I am having trouble trying to start clapping the way you suggested ( I can't snap my fingers).
Most of the time I have trouble understanding which of my decision were mine or automatic and there are just so many decision made in a day that I feel overwhelmed.
