Regarding “Death”...... I can conceive of no difference, potentially distinguishable by me personally, between the lack of “existence awareness” which characterized my “pre-birth” period.... and that same "non awareness of existing" which still occurs often in deep sleep..... and that imagined "state of non awareness" that will likely occur upon completion of my life. Same thing! If "I" am not "aware" of existing...I don't exist! So far in my life, I do have memory of multiple previous episodes of "non awareness", but if this "subsequent memory of previous non awareness" pattern ceases.....I'll never know it!
