  1. Short-term and long-term memory are “managed” by different areas of the brain. In short-term memory, of course, everything that happened to a person is stored (usually in an ordinary person), but it is quickly replaced (overwritten) by other, more recent impressions. And often something completely skips past our perception (the brain selectively processes incoming information). That is, even from what happens in real life, we do not remember everything – the older the event/impression, the (on average) we remember less about it. And now the question: what is the value of sleep? Why does she remember him? “No need. The main purpose of sleep is to experience a certain “virtual” experience, it is training the brain. Roughly speaking, the ability to remember dreams well did not give our ancestors an evolutionary advantage over relatives who remembered dreams worse. You remember your dreams well, you remember your dreams poorly – this did not affect the probability of success in transmitting your genes, so we usually remember only what we dreamed exactly before the urge, because short-term memory. The correct question is memorized as follows: why do we not remember our dreams for a long time? Because the question “why do we forget” implicitly implies some special action for forgetting, which in fact does not occur. And we do not remember for a long time because there is no profit (evolutionary=)
