Source passage

Source text · mention only

He records the answers of fourteen totally blind persons who lost their sight previous to their fifth year, and _none_ of these has dream-vision. Of four who lost their sight between the fifth and the seventh year, one has dream-vision; one has it dimly and occasionally; and two do not definitely know. Of thirty-five who became blind after their seventh year _all_ have dream-vision. The two independent researches thus yield the very same conclusion. Dr. Heermann includes in his list many aged persons, and from their answers is able to conclude that, generally speaking, those who become blind in mature life retain the power of dream-vision longer than those who become blind nearer the critical age of five to seven years. He records twelve cases where dream-vision still continues after a blindness of from ten to fifteen years, four of from fifteen to twenty years, four of from twenty to twenty-five years, and one of thirty-five years.
