Can death be conquered through sleep, similar to the state achieved in meditation or sadhana?

According to Osho, conquering death means realizing there is no death at all. Sleep and meditation reach the same inner 'place,' but in sleep you are unconscious, so nothing is truly known. Only conscious awareness—through meditation, or full wakefulness even in sleep—reveals deathlessness and ends the futile struggle with death. Thus, sleep alone cannot conquer death; awareness does.
