"The sleep of narcoleptics is abnormal and characterized by: a short sleep latency; frequent sleep onset REM periods (i.e., REM sleep begins within 30 minutes of going to sleep); REM period interrupted by arousals; higher than normal amount of time spent in stage 1 but less than normal amount spent in slow wave sleep; and frequent arousals from sleep. This results in the patient suffering regularly from very poor quality sleep which can lead to many cataplexy attacks during the day despite the use of prescribed stimulants.
Their brain is simply exhausted and is unable to recover or repair during the night as the patient cannot maintain quality slow wave sleep.
GHB counteracts these abnormalities by increasing slow wave sleep, lessening stage 1 sleep, and reducing arousals from rapid eye movement (REM) sleep.
Simply put, they spend less time in “shallow” sleep and more time in the reparative slow-wave sleep stages (“Deep” sleep).
One similarity in an otherwise healthy person is the parent of a new-born baby. They will likely experience a similar state of regularly interrupted sleep which reduces their ability to reach and maintain the slow-wave stages which can lead to extreme states of mental exhaustion during the day. Although at least they will, eventually, recover as soon as junior can sleep through the night regularly!
In fact, as a quick asides, there are many, many, physiological problems that are the direct result of a poor night’s sleep. Even though a person may be unaware of the poor quality sleep they are frequently experiencing, stress, worry, environmental factors (excessive noise, light etc.) and drug abuse can easily result in a night’s sleep consisting of bouncing between stage one and REM sleep without properly reaching the reparative stages.
After a length of time, there can be serious implications for the person who is frequently unable to reach and maintain quality slow-wave sleep."
Do i need to say more? i am CONSTANTLY dreaming and when i wake up i am often not tired, as if i never fell into a deep sleep.
