We spend the majority of the night in Light sleep. Light sleep is similar to being awake in that we can talk, move, and regulate our body temperature while we are in Light sleep. We also dream, but our dreams in Light sleep aren’t the fully formed stories that we usually characterize as dreams. Instead, our Light sleep dreams are flashes of memories or images that usually don’t form any coherent narrative.
Light Sleep is the closest sleep stage to being awake, and we are most easily awoken during this stage. If woken during Light sleep, you might not even have noticed that you were asleep. It is ideal to wake up during Light sleep, as you will be able to wake up much more easily and feel more alert than waking up in either of the other sleep stages.
