Is it easy to dream about ghosts when sleeping at five o'clock at night?

It is not easy to dream about ghosts when sleeping after five o'clock at night. There is no need to make a fuss about dreaming. Because the right hemisphere is dominant when dreaming and the left hemisphere is dominant after awakening, the dynamic balance between nerve regulation and mental activity can be achieved by alternately waking up and dreaming during the 24-hour day and night activities of the body. Therefore, dreams are a way to balance people's psychological world, especially for people's attention, emotions and cognitive activities.
