Generally speaking, after a hard day's work, people should have a good sleep at night to get rid of the fatigue of one day and prepare enough energy for the next day's work. I dream when I sleep. If you work smoothly during the day and feel comfortable, you may have happy and relaxed dreams, such as dreaming of promotion and salary increase, dreaming of lingering with your lover and not wanting to wake up. On the other hand, if you are in a bad mood or exhausted, you are sure to have some disturbing nightmares. For example, I dreamed of quarreling with leaders and dreaming that things were stolen by bad people.
Dreaming sometimes indicates what will happen to you or around you. It may be a happy thing or a troublesome thing. If you dream of rain, big fish, blood spatter and so on. It is a good dream that indicates good luck, either getting rich or getting a raise. If you dream of falling into a pit and being bitten by a dog, it indicates that the villain may be in trouble, so be careful.
The dream described above appears when you sleep for a long time and deeply. Daydreaming, a short nap, was awakened by the alarm before she fell asleep. Therefore, dreaming during the day is just a joke, and it has no effect at all.
