The researchers discovered that sounds featured often, being reported in 80% to 100% of each participant's dreams. Most often, the sounds consisted of other people speaking. (There were even five instances described as speech in a foreign language that the dreamer did not understand.)
The participants reported auditory impressions in 93.9% of their dreams on average. The most prevalent auditory type was other people speaking (83.9% of participants' dreams), followed by the dreamer speaking (60.0%), and other types of sounds (e.g. music, 33.1%).
This happens because during the dream our sub-consciousness is activated, as well as the memory related to all the senses. Sounds, which we do not remember, are registered somewhere deep into the sub-consciousness and this memory is triggered in the dreaming state.
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.

You may need to listen more – or take time out from a difficult situation to examine it. Silence can be focusing your attention on what is missing in your current approach. There may be an element that you are not seeing because you are not taking the time to reflect.
The inability to scream, as well as run or punch someone in your dream, appears because your brain areas that control motor neurons are switched off during sleep,” explains Julie Lambert, a certified sleep expert from Happy Sleepy Head. “Motor neurons are responsible for any muscle contractions.
Science says that we lose consciousness everyday at night in a dreamless sleep. Whereas Vedanta says the dreamless sleep feels like there is no consciousness because of a lack of object without which self-awareness (I know I exist) cannot happen. The dreamless sleep is a form of pure consciousness without any object.
Sometimes the dreams we have seem so real. Most of the emotions, sensations, and images we feel and visualize are those that we can say we have seen or experienced in real life. This is because the same parts of the brain that are active when we are awake are also active when we are in certain stages of our sleep.
Our Brains Are Listening While We Sleep
Not only that, but we are listening for certain sounds while we sleep, even when we're in deep sleep. For example, we grow accustomed to the sounds that usually fill our home during sleep. This includes the hum of the fridge, or the heating or cooling system turning on and off.
You might think that sleep talking occurs during dreaming. But scientists still are not sure if such chatter is linked to nighttime reveries. The talking can occur in any stage of sleep. Sleep talking usually occurs by itself and is most often harmless.
Some Deaf people have an auditory component in their dreams
If people become Deaf after the age of five, they will probably have an auditory component in their dreams, even after a severe hearing loss. This might range from short auditory flashes to complete auditory recreations.
Exploding head syndrome (EHS) is a type of sleep disorder in which you hear a loud noise or explosive crashing sound in your head. The sound isn't real or heard by anyone else. The episode typically happens suddenly either when you're beginning to fall asleep or when you wake up during the night.
Hearing in Your Sleep
It's exciting to learn that our ears and brain can process sound even when we're sleeping! You might not remember it in the morning, but your brain is keeping track of the sounds around you. You may even be able to learn new things during Stage 1 and Stage 2 sleep.
Overall, researchers and study participants agreed that black and white dreams were the norm, and rare cases of coloured dreams were dubbed 'Technicolor' dreams (Calef, 1954, Hall, 1951), highlighting their perceived artificiality. This tendency to report black and white dreams suddenly disappeared in the 1960's.
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.
People can say all sorts of strange things in their sleep, but a new study suggests that someone in the middle of a vivid dream can understand questions – and even answer them.
Catathrenia is the medical term for groaning during sleep. Persons with this condition emit long, sometimes loud groans on exhalation or out-breathing, most commonly during REM or deep sleep.
1. Sleep disruptions: Vivid dreams that linger with you or feel indistinguishable from real life may be the result of fragmented sleep. Waking during a period of REM sleep rather than at the end of a sleep cycle can cause you to remember your dreams more vividly.
The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes. People are more likely to remember the dream if they are awakened during the REM phase.
Experiencing recurring dreams may point at underlying issues regardless of the dream's content. Adults who experience frequent recurring dreams tend to have worse psychological health than those who do not, and many experts theorize that these dreams may be a way to work through unmet needs or process trauma.
During most stages of sleep, the thalamus becomes quiet, letting you tune out the external world. But during REM sleep, the thalamus is active, sending the cortex images, sounds, and other sensations that fill our dreams.
We lose consciousness when we fall asleep, at least until we start to dream. This is the default view and it asserts that there is conscious experience in sleep only when we dream.
Death is “merely” a step beyond sleep. That is when for the higher self's purpose, the soul is drawn into a permanent state akin to sleep. One from which it is impossible to return.
