It is never good to have absence of deep sleep or dream sleep. But most people will enter into all stages of sleep unless they are taking a medication that suppresses that particular stage of sleep or have a sleep disorder that prevents them from entering REM sleep or delta sleep. You need all of your sleep stages to feel normal and feel refreshed the next day. Can night terrors be a temporary problem. It seems like the screaming in my sleep only lasted a few months and not very often.
Night terrors can be a temporary problem.
Most often night terrors are a problem of childhood and people outgrow them. They may reappear, as we grow older if there is something that is disrupting our sleep, Often minor arousals cause us to have night terrors, if those arousals occur during deep sleep. So we often see night terrors appear in adults if they are exposed to a stressful experience or if they develop a new sleep disorder such as sleep apnea, which may be disrupting their sleep. Unfortunately we are just about out of time. Everyone sleeps, but not everyone sleeps well, and so most people experience sleep disorders at some period in their life.
