To see a book or film character is a signal to change something in your life to be more successful and happy. It all depends on the genre of the film or book and the features of the character.
A comedic character – do not take everything too seriously
Horror movie character – unexpected event, but it will not scare you
War film character – you need to relax and take some days off
Crime story character – secret knowledge
Romantic movie or book character – love adventure
If you are not participating in dream events, but just watching them – changes will come to your friends and family. If you participate, changes in your life will occur.
