If two people are colleagues or lovers, they have been thinking and discussing something for a long time at work or in life during the day, and their brains are still in this relatively excited state at night, it is easy to have more consistent dreams. For example, two students are about to have an exam, discuss the same topic for a long time during the day, or are very nervous about the upcoming exam, and may unconsciously dream about the exam-related content at night; If a worker discusses a job for a long time during the day, he may also have a dream similar to work at night.
Second, two people live in the same environment.
This situation is mainly reflected between couples or relatives. If you are husband and wife, living under the same roof for a long time, both sides are already very familiar with living habits and working methods. Both sides can understand each other's thoughts even if they make eye contact, so it is very normal to have the same dream at night. If father and son or mother and daughter sleep in the same bed, play together during the day and do very close parent-child activities, they may dream of similar situations at night.
Thirdly, I met something equally exciting.
This situation is mainly manifested in stimulating nerve cells in the brain and making the brain too excited. For example, going to the playground, many people will go to the playground to play. More exciting games on the playground will give the brain a very strong stimulus, and it is easy to appear on the playground at night. In addition, if there is a fire somewhere during the day and there are many onlookers, the fear among the onlookers will react to this exciting thing and have similar dreams at night. In other words, visually everyone accepts the same thing, and it is possible to have the same dream at night.
