At this stage, the person who is being woken up is not aware that he is asleep and may say that he is not asleep. It is a part that constitutes 45-55% of sleep time. The mobility in the muscles decreases slightly.
Third Stage
Sleep becomes deeper. The mobility of the muscles has decreased considerably. Instead of theta waves, it begins to emit delta waves. Slow eye movements may be seen. It constitutes 20-25% of the general sleep time. Delta waves are the lightest and most common waves. This phase can also be called slow wave sleep.
Fourth Phase
