I think kev5 has said it very nicely. You are seeing the manifestations of your energy flowing more freely. You are moving towards a freer flowing and more balanced system. You could try and analyze it and figure out what is going on, and you might even come to the right answers. But does it really matter? When you know that what you need to do is continue your SFQ practice to make things better.
I could ramble on about what I think is happening, using some ideas about belief systems. Or I could talk about some of the recent ideas I've read about on Budhist (is it one or two d's, I've seen both), about ideas creating confusion to ensure their continued existance. Or Arnold Patents ideas about hiding the truth from yourself.
These ideas will all come down to recommending that you do fundamentally the same thing you do, by following SFQ. So you can cut to the chase and do as Master Lin suggests and "stay with the meditation".
I too have had negatively label emotions bubbling up lately. I have chosen, for the most part, to deal with them just like I deal with distracting thoughts during meditation. I smile at them and say, "that is not when I choose to direct my thoughts and energy", and allow them to dissolve or float away or leave in some other peaceful form. (being a good Jedi, ya know)
You are perfection; really.
