So the summary is as follows:
1, there is no doubt that "thinking about it day and night" may be that you thought of such a thing in the morning, but your memory is not very deep. Scientific research has proved that the first and second REM dreams are mostly recurring experiences in the morning, so this one should be ruled out first. In the third and fourth REM sleep, there are often past experiences and old scenes in dreams, but this is not the case. In other words, it should be the last and fifth rapid eye movement period. In the water, time and space are intertwined, the scene changes, and the fantasies experienced by the present and the past are mixed together, forming a very bizarre dream. Of course this is normal.
2, the main reason for this nightmare is that the body is often not very healthy, or the mental stress is too great. People who feel uncomfortable usually have nightmares, such as myocardial infarction or angina pectoris, and usually dream that they fall from a high place. If the mental stress is too great, you can travel or relax, in short, don't make yourself too tired; Or see a doctor (if you think it's necessary) to see what's wrong with body organs or something.
Tell you three ways to avoid nightmares.
First, it must be to control the sleeping position. According to research, lying on your side is good for your health.
Second, remind yourself that you are dreaming in your dreams.
Third, self-suggestion, using implicit methods to control the people in the dream, let them advocate their own behavior, that is, let them do what you are doing. Interspersed with some content, the most straightforward expression of this dream is lucid dream. People who have lucid dreams can do whatever they want in their dreams.
Fourth, the ancients said, "Don't do anything wrong, you are not afraid of ghosts knocking at the door." This is the truth.
