What might someone be thinking heading towards death?like when a parashoot doesnt open?

i sort of meditated on this this morning... I imagined what it would be like to plummet toward the ground, and know that i was going to splat.... i struggled for a moment and then let go completely, and thought of my mom, and of earth, and nothing.... then came an intense struggle again..... then thoughts of pain, then thoughts of adreneline.... then a sort of relaxed resigned, very distant , sort of medatiative state... kind of strange hunh? i'm just wondering what people think when they know they are going to die.
