Good evening, thanks for asking at HealthReplies.com. To be able to answer your question, you need to understand that sleep is quite complex and consists of various levels of awareness. Lay people might think there are only two conditions, namely sleep and not sleep. But in more detail, there are several steps to arrive at a truly deep sleep stage.
In general, the phase in sleep is divided into two, namely NREM and REM. NREM can then be further divided into 3 phases. Some sources divide it into 4 phases. Of the three phases, the first phase is the phase where our consciousness is still the highest. We can still hear people around us, know the changes in light, and so forth. The second phase will be deeper, the third phase deeper, until it enters the REM phase, the phase in which people experience dreams most often. In this phase, the senses cannot catch any stimulus, breathing is very slow, heart rate decreases, muscles relax, and you are completely unaware of anything around you. All of these phases occur repeatedly in the sleep cycle throughout the night, so after REM, it will go to NREM again, to each phase then to REM again and so on.
So regarding your question, it is very possible that someone seems to be asleep, but can hear the words of others, which means sleep is not deep. This impact is the body's recovery when sleep is not optimal, because the body is not fully rested. Usually people who are not deep sleep, will not feel more refreshed in the morning, even more tired.
If you are one of those who are experiencing fatigue, check yourself with a sleep disorder sub-specialist psychiatrist for further examination. But if you have not been disturbed, no problem with it and you do not need to worry. So, hopefully answering your question.
