Some people dream a lot when they sleep, while others rarely do. People who dream a lot tend to worry, is it insomnia to dream during sleep? Generally speaking, dreaming during sleep is a normal physiological phenomenon. Our sleep is not from falling asleep to waking up, so two stages. Sleep is divided into stages 1, 2, 3, 4 and eye fast moving stage. Stage 1 is the lightest stage of sleep, and through stages 2 and 3 we enter stage 4, the deepest stage of sleep, and then we enter the oculomotor stage. The oculomotor phase differs from the other phases of sleep in many ways. It is during this period that the sleeper’s eyes, which are normally stationary, begin to move in a rapid manner, hence the term oculomotor phase, and it is during this phase of sleep that our dreams occur. Our phases 1, 2, 3, 4 and the oculomotor phase are repeatedly cycled several times during our night’s sleep, each cycle lasting about 90 minutes. In this way you understand that dreams often occur after deep sleep stage 4. So dreaming is not a criterion for sleep disorders. As long as you wake up refreshed in the morning, dreaming is nothing to worry too much about.
