What are they?
Well dreaming is an important part visit this site of sleeping. Dreams are images, ideas, emotions and sensations that occur in the mind during sleep. Our dreams can be influenced by what we’re doing during the day and what we are feeling about different situations.
We spend our days gathering information and if we do not clear out our mental storage space regularly we risk saturating our brain with too much information. In order to fully process this, we need to shut our brain down and disconnect it entirely from the outside world and that is called dreaming. Getting into that dreaming stage can help you processing information and emotions, helps with memory, concentration, coordination and mood swings.
Dreams can last from as little as a few seconds to as long as 20 minutes, and the average person has at least three to five, and often many more, dreams a night (dreams typically occupy a total of about two hours of a normal night’s sleep).
We tend to dream in two stages of sleep. The first stage is the slow wave sleep (SWS) and the other is called rapid eye-movement (REM) sleep.
As you can see in the image below SWS is stage 3 and REM is stage 5 (most likely to dream more here).
This image below shows you what a healthy sleep looks like. You will go in and out of stages all night.
People suffering with sleep apnoea unfortunately don’t always reach the REM stage of sleep as when an apnoea occurs the body wakes up and puts you back into the first stage. This is why people suffering with sleep apnoea may sleep 8 hours per night but wake up tired as they are not getting into that 5th stage of sleep to make you feel more refreshed and not tried during the day.
If you are having troubles sleeping please see your doctor or health care professional.
Scientist are still researching dreams and why they happen and why we dream what we do…
