The man dreamed that he was urinating in the toilet

Dreams have nothing to do with good luck or misfortune.

Many people have such troubles: after falling asleep, they often have nightmares and even wake up. Due to poor sleep, the next day I felt dizzy, which affected my work and study. Some also worry that nightmares will bring bad luck to them, causing psychological fear and uneasiness.

In fact, dreaming is a normal psychological phenomenon produced by people during sleep. Under normal circumstances, the nerve cells in the brain are in a state of inhibition during sleep, and this inhibition process is sometimes relatively complete, sometimes not complete. If it is not completely suppressed, there are still a few areas of the cerebral cortex where nerve cells are excited, and people will have dreams.

Because the activity of a small number of cells loses the control and regulation of the entire cerebral cortex during the wakefulness state, certain fragments of memory become active unfettered, and may manifest a variety of strange dreams that are different from normal mental activity. At this time, if the nerve cells involved in language and movement are also excited, not only dreams will occur, but they will also talk or sleepwalk.
