Do You Hear Everything When You Sleep?

Date: 27 May 2022 | By: hale

Have you ever dreamed of sounds such as music or crying? Then you wake, and the noise is happening in reality. Does that mean you really heard the noise while you were sleeping?

Yes, it does.

Stages of Sleep

Every time you sleep, you go through four different stages. Each stage of sleep plunges you into new depths of rest, and they invoke changes in heart rate, temperature, breathing, and brain activity.

Stage 1

This is where you start to fall asleep. You have not relaxed quite yet. In this stage, it is normal for your body to twitch. It can also be very easy to wake up.

Stage 2

At this point, your heart rate, breathing, and body temperature drop. Your brain waves begin to slow down, and because your body functions are slowing down, it is harder to wake up from this stage of sleep.

Stage 3

Stage 3 is categorized by deep sleep. Your breathing and heart rate slow down even further, and your body uses this time to heal and recuperate from the traumas of the day. It also boosts your immune system and helps consolidate memories.

Stage 4

Also known as REM sleep. Your brain becomes very active, almost as if you were awake. Your breathing picks up, and your eyes move back and forth under your eyelids. REM sleep is important to cognitive functions, learning, and creativity. This is the time you usually have life-like dreams.

Do You Hear Everything When You Sleep?

Scientists recently discovered that your brain does not ‘shut off’ when you go to sleep. It continues to pay attention to the sounds around you and will pay closer attention to certain noises. As you sleep, your brain will listen to what is going on and decide which noises to pay attention to.

The practice of hearing while you sleep mostly happens during Stages 1 and 2. Once you enter deep sleep, it seems to erase any memory of what you heard during Stages 1 and 2.

People often wake from dreams and wonder if what they heard was just in their dream. As you sleep, your body hears everything around you. The sounds are filtered in your brain and given a rating as to how important it is. A sound may be ignored or even integrated into your dreams; cue the alarm clock sound becoming elevator music. Yet, depending on the urgency of the noise, it could even wake you, i.e., the bump in the night.
