SLEEP AND DREAMS EXPLORED 2 Sleep and Dreams Explored Introduction Sleep is defined as a state of having a recurring relaxation whereby the body becomes temporarily unconscious, body senses become inactive, and the communication with external entities becomes reduced. While in sleep mode the body can build up and reinstate the immune, muscular, skeletal and immune systems. Several factors can cause sleep. For example, sleep can come as a result of tranquility. When an individual is in a resting mode in most cases, sleep comes. Sleep can also occur as a result of being tired (Sleep and tiredness, 2019) . In such an instance sleep grows to the deepest stage where dreams happen. Another cause of sleep is when an individual has adapted to sleeping at a specific time. Chances are when this specific time comes the person will often get the urge to sleep (Groth & Kryger, 2019) . However, sleep develops into different stages to which it alternates into the rapid eye movement (REM) and the non-rapid eye movement state (non-REM). When a person is sleeping the brain is always active. When the brain is measured electrically, it releases some electric discharges that have wavelike designs which change their height systematically(amplitude). These amplitudes move at a systematic speed called frequency (Nielsen et al., 2015). There are four sleep stages, and it takes approximately ninety minutes to advance from stage one to stage four. At all these stages the brain wave patterns are distinct relative to the body activeness. The following are the four sleep stages: Stage One. This is the first state of sleep in which there is relatively low eye movement. At this stage, the body is in a non-REM state, and a little disturbance can make an individual awake. Images
SLEEP AND DREAMS EXPLORED 3 may seem as if they were still which is not an actual dream. One feels drowsy, and the body muscles start to relax while the brain waves commence slowing down different from an awake state. In most of the times while sleep is progressing to stage two an individual may experience involuntary muscle twitches and even a falling sensation. The stage takes only a few minutes (Nielsen et al., 2015). Stage Two. This is the real stage of non-REM sleep. At this stage arousal from a slight disturbance does not happen. The movement of eyes now stop, and brain wave amplitudes become bigger as compared to those at stage one. Sleep spindles and K-complexes start occurring, and they are said to be a brain development that protects body sensitivity from awakening. The body heartbeat starts to slow down with reduced metabolic functions and temperatures decreases. Stage one and
