It may seem like sleep is one continuous stage, but it really isn’t. Our sleep is divided into five stages, all leading up to the final stage; REM sleep.

In stage one when we are about to fall into nightly slumber, we have periods of dreaminess, which is somewhat like daydreaming. We also experience strange and vivid sensations or a feeling of falling followed by muscle contractions, these are often called hypnagogic hallucinations. We then begin to enter Theta, which is a light period between being awake and asleep.

Stage two lasts for roughly about 20 minutes. Our heart rate starts to slow down and our body temperature drops. Our brain will also start to send out short periods of rapid rhythmic brain wave movement known as Sleep Spindles.
