Cellular memories are the memories that have been stored within the cells tied to activities, and accessibilities due to the different scenarios in which one's been through. Some more heightened than others, some more emotional than others, that have locked these memories into the cells, some for survival, some for bliss. That's why at times you feel so euphoric, that's when the cells are beginning to work together again, and move forth together again, going beyond the memories of the cells but stepping into you and allowing for the cells to dissolve themselves of the physical makeup of debris that have been locked up within them from emotions, etc.
