Tertullian

“ If indeed such a thing were told me to have happened at any time to the soul—resembling a total eclipse of the sun or the moon—I should verily suppose that the occurrence had been caused by God’s own interposition, for it would not be unreasonable for a man to receive admonition from the Divine Being either in the way of warning or of alarm, as by a flash of lightning, or by a sudden stroke of death ”

“ What indeed would be said, if the case of Hermotimus were believed to be such that the repose of his soul was a state of actual idleness during sleep, and a positive separation from his body? You may conjecture it to be anything but such a licence of the soul as admits of flights away from the body without death, and that by continual recurrence, as if habitual to its state and constitution. ”
