What should I do if I often have nightmares

Call her every day and try to find time to chat with her before going to bed at night and say something very relaxing. Let her pay attention to her sleeping position. Bad sleeping posture can also lead to nightmares. Tell him that if there is a ghost looking for her in the dream, let the ghost come to you and you will always accompany her. Ask her if she has been under pressure recently. If she is in a bad mood, she will have nightmares when she is stressed. Also, let her give herself some psychological hints to make herself brave. If you can face your fears bravely in real life, you won't be afraid in your dreams. If it's a horror movie, try to make her watch less. Pretending to be a ghost is scary. Next time she asks you to watch a horror movie, you should try to distract him and do something else with her. Love her and make her depend on you.
