Proverbs and themes differ from proverbs in the first place, that situations for their application are much greater. Take, for example, the well-known expression "the mosquito does not undermine the nose". Its meaning can range from "no one will know" to "everything will be fine". Proverbs necessarily contain a conclusion, and sayings can be used "to the word" and be multi-valued. So, in what cases is it appropriate to use the saying "less you know - you're sleeping more tightly," and what is meant by this?
What prevents sleep soundly?
This expression is completely wrongly called a proverb, because no sane person will take to the direct action the words "less you know - you sleep more tightly". Otherwise, he would have to give up any knowledge for the sake of healthy sleep. But the multiplication table or the rules of the Russian language is unlikely to lead anyone to insomnia. So what kind of knowledge that prevents night-time rest is spoken of in the saying? To do this, you need to consult an intelligent Dictionaries and see the lexical meaning of the word "know". It seems to everyone so elementary for everyone that it never occurs to anyone that in connection with it there may be some misunderstanding. And still. For example, in the dictionary of the XVIII century "know" had eight meanings, the main one of which was the availability of information, news about something. In the modern Russian language in the dictionary of Ephraim, the verb "know" five meanings, the first of which denotes knowledge, the second - awareness, the third - familiarity with someone, the fourth - experience, the fifth meaning (portable) is used in the sense of guessing. So now it is easy to conclude that the saying "you know less - you're sleeping more tightly" does not call for ignorance, and it's not at all about scientific knowledge in it that one of the variants of using this expression in its direct meaning, but with a touch of irony, nevertheless exists. It will be in the event that suddenly in the class one of the students, who also learns badly, falls asleep. It is in this situation in the expression "less you know - the more you sleep" the verb "know" will be used in the sense of "possessing certain knowledge and skills."
Sleep that is not a dream
Is it always about a sound dream in this saying? A person's sleep is disturbed by increased anxiety. And all sorts of guesses, experiences and information that lead to suspicions and reflections lead to it, even to know someone and that is "dangerous" for sleeping. But is this saying always a dream in the literal sense? When a woman buys an expensive handbag, when asked by a friend about how her husband will treat this waste, she answers: "He knows less - he sleeps more tightly". With this phrase the lady immediately makes it clear that she will not say anything to her husband. In this case, the proverb has a slightly different meaning: the desire to hide some information from a person so that he does not ask unnecessary questions, there is also a clear desire to make a decision without consulting anyone. But when the seller, changing the curry sticker on the shelf-life label, says: "You know less - you sleep more tightly," then at least it goes to forgery, so it can happen if it does not matter, then it's a big trouble. So it is possible to assume that someone with this saying goes even to a crime.
