Yes, we have had this subject up before. . . of course, as new members come, subjects which have been well beatened out and have retired from sight, come up again; as they are on the new member's mind, and the newer member has not checked deeply enough for similar threads.
I agree that Freud and Jung's anaysis base is misinformed to the larger degree, and thus not so factual. The nostalgia of their proposals, and the fact that their counseling often did help (overall), keep yet a good number of psychologists clinging to their camps.
Many things seem to occur during sleep, and one of them, perhaps the number one major thing, is the repair of worn and damaged brain parts. . . yeah, we lose them parts too. Another major thing to keep in mind when you dream of sleep and dreaming, is that the brain does not stop working. . . no one dies while they sleep (in the sarcastic sense here only) so don't go fretting going to bed tonight. You'll wake up after the alpha wave sleep, as though nothing had happened while you were lacking consciousness, at all. Or is that what dying is, basically? (of course it is !!!--as will be discovered on another thread some sunny day)
