There is no "me" there even during a contraction. That's also a mental image. In fact, I can't find a "me" anywhere. And it could never have been there, as my raw experience was always awareness plus perceptions in all forms.Can you reproduce this sense of contraction by recalling or imagining one situation that has caused (causes) it and please take a look at how it is related to "me"? Please describe the sensation as it is and what is its relation with "me". Please try to be as brief and clear as possible in this description and try to stick just to what it actually is, eg. please try to filter out what some mental images might say about how the sensation happens.
All the best, Yev
