A 2016 study took a close look at how the brain processes sounds while you're sleeping. They found that during light sleep, such as during short naps or when you're first falling asleep, you are still processing the things you're hearing. You can even hear and process words that you hear while you're in light sleep.
The answer is fairly straight forward: while we are sleeping, our ears continue to collect 100% of the sounds around us. It's our brain that reduces the processing of sounds to a minimal level. It is because of this continuous processing of sounds his during our sleep most people prefer a quiet bedroom.
The study concluded that people do hear while they're sleeping! And we even process the sound we hear, and decide which sounds to pay attention to. This happens the most during Stage 1 and Stage 2. In another study, participants listened to words during short, light naps.
This study reveals that the brain responds to external sounds, meaning that you can hear while you sleep. This also aligns with the stages of sleep where the brain is more active during certain phases over others.
During sleep, our body can decide to ignore sounds, movements and smells happening around us which might otherwise wake us. This decision-making mostly happens in our brain.
If you think you're seeing — or smelling, hearing, tasting, or feeling — things when you're asleep, you may not be dreaming. It's possible that you're experiencing hypnagogic hallucinations. It's more likely if you're waking up in extreme fear that your hallucination was real.

Overall, the study provides evidence that auditory content is frequent in dream experiences, most commonly taking the form of other characters speaking, followed by the dreamer speaking and finally, other sounds.

If you've ever been in this awkward situation, you might have experienced “microsleep.” This weird state of consciousness is characterized by brief bursts of sleep that happen while a person is awake — often while their eyes are open and they're either sitting upright, or even performing a task.
