You cannot control dreams – they just happen.

Over the years, many have tried to interpret dreams, but there is no evidence to suggest that any of the common symbols mean anything (e.g. REM sleep dreams tend to be more memorable and often weird as your brain processes past events and emotions.

REM Sleep Importance (and Dreams!)Īs you know, dreams are a series of images, sounds, and emotions that occur while you sleep. The question of muscle tone remained, as did all the questions about how and why dreams happen. Some theories suggest that this happens so that we won’t hurt ourselves by trying to act out our dreams, but in recent years, the theory has lost steam. While the brain shows the degree of activity parallel to wakefulness, the body remains still during the REM phase. REM sleep is also associated with memory consolidation (which shows WHY getting a good night’s sleep before your exams is important!). While dreams can happen in non-REM sleep, too, they are most vivid and memorable at this time. Your heart also beats faster (and sometimes irregularly), and most commonly you experience dreams. During this phase, your muscle tone stays low while brain activity increases. REM sleep comprises about 20-25% of your sleep cycle. It can happen in several subsequent instances, with the first lasting several minutes and the others getting progressively longer. Rapid eye movement sleep is the final stage of the sleep cycle.

The deep sleep stage is responsible for waking up refreshed, although there are indications that this is when the brain clears up memory paths to foster better memorisation of what happened the previous day. Your body temperature drops, your eyes and muscles stop moving, and sometimes you even get attacked by sleep-paralysis demons. This is the longest stage of non-REM sleep, and your body takes it as the best chance to fully relax. Although they show on an EEG scan (electroencephalography), they do not manifest physically, and so far, science has not given us all the answers about why they happen. Sometimes, sleep spindles occur – these are somewhat peculiar brainwave frequencies associated with learning and controlling sensory functions. Your muscles alternate between tone and relaxation, the brainwaves slow down, and the eyes stop moving.

Stage 2 prepares your body for deep sleep.

This is also when your muscles sometimes jerk – it’s because there’s some pent-up tension in them, which is released in a so-called hypnic jerk. You know the sensation: you’re not quite asleep, so you hear your flatmate sneaking into the kitchen for a late-night snack (probably the last of the Oreos you had your eyes on), but you’re also not quite awake to do anything about it. Usually, the first stage doesn’t last longer than ten minutes, and it’s easy to wake up at small disturbances. This is the time between wakefulness and transitioning into a deeper sleep. To remind you, these are the stages of a sleep cycle: Non-REM Sleep The REM sleep phase happens at the end and is one of the most fascinating displays of our brain activity. Each sleep cycle is divided into several stages of varying lengths, during which the body relaxes, recovers, and replenishes its energy for the following day.
