a
reference to a so-called "teaching" device, that consisted of a record player and speaker. The speaker was placed under one's pillow and a record containing suggestions or
information to be
learned was "listened to" while one slept. They have, I think, something that's called a Dormaphone or something like that.
a record player device which played
data to an
individual while he slept, the idea being that he would retain the
data when he awoke. Dorma means "sleep," phone means "
sound."
