1. Find a cool notebook and write down your daily mood or strange things in your eyes with black ink pen, or stimulate the second personality to come out with extreme words. Maybe one day I will regain my second personality.
2. Give the second personality a name, sit and close your eyes, and imagine yourself calling for the second personality. After 15-2 minutes, you will see a figure when you open your eyes. When you close your eyes, you will look like a second personality. Try to communicate with the second personality and try to understand how the second personality feels about the main personality.
Extended information:
In daily life, the formation of dual personality is mostly related to the living environment. When the surrounding environment produces too much negative influence and pressure on one's own subject, which can't be solved in one's own mind, one may make one's heart escape from real life and fantasize about another personality that one can accept, so as to relieve the pressure and obtain psychological balance.
So, in other words, dual personality is also a defense against environmental pressure. But in the long run, it is easy to have personality defects, which makes the subject unable to change his personality independently. So in life and work, add less unnecessary pressure to yourself.
