I think that the only thing flashing before your eyes is the thing that matter the most to you. You have no desire to remember your life. You lived it and that I think is enough for most 🙂 I imagine you see the things that define your passions in life. Be it a lover, a child or God.
I believe you see your purpose in life 😄 You maybe remember your whole life but as a feeling and not as images flashing by. You feel the life you have lived and you see the thing that define living to you 😛
