Strange feelings after meditation and mindfulness practice?
I don't think you are alone in this. Susan Blakemore in her excellent book Zen and the Art of Consciousness describes almost this exact situation. She paid attention in her everyday life just as you have done and found it very illuminating. However after two weeks of this she reach a point when she couldn't cross the road. She was paralysed as you were. She abandoned this 'experiment' and went back to her meditation and retreats the results of which she details in the book. 

I hesitate to give advice in your case as I am woefully unqualified to do it. However it does seem you are having trouble integrating you experiences, you might even be have a kind of alienated awareness experience where you are very aware but not emotionally connected. I think with all these practices wisdom and compassion need to be balanced. I would be tempted to back off a little and engage with some metta type practices - kindly awareness towards yourself and others. But please disregard this - it's only what I would try.
