Had a similar experience during meditation this morning. I got into a very nice, deeply relaxed state when I started feeling some fear arise in my solar plexus. At first, I asked myself, "Why is this happening now?" But then I realized I had been repeating some affirmations around financial stability and security and remembered what you said in another of your stories about how unprocessed emotions often arise during meditation. So I figured that's what was happening and simply observed the feeling instead of mentally wrestling with it. It eventually dissipated.
