True or False

One of the myths I had heard more than once was “Learn while you sleep”, so I was very delighted with the idea to know the truth about it, so let me tell you what I could learn of this mystery.
I began to explain you what it is, so this method suppose that if you hear information repeatedly while you are sleeping from a tape recorder or a CD player, you can retain the most part of the message effortless, it looks really easy! But sorry unfortunately it is a big lie!
There were some theories that support it but all had in common to be very vague and contradictory, in fact there are no one with a scientific study that proves this assertion. One of them said that is more efficiently learn during sleeps than while awake, but not only said this madness because the reason of it is crazier, it could be because an unconscious process is the first step in the activity and so a person awake would be on the side of learning.
There are no doubts, learning is more complex than you think, it isn’t possible that a simple repetition without effort will be the secret to learn whatever, you need a conscious process and of course that the best isn’t be asleep.
When I read all this I was very surprised because I thought there was some help, something that could stimulate the process, but it was a lie, I can’t understand how people continue making lectures about this in spite of it is false, that proves the lack of information in the world, sometimes people believe everything they hear and it is really necessary texts like this to realize the media don’t always tell the truth of the facts.
