I'm sorry to hear about your struggles with nightmares and sleep disturbances. Dreams, especially recurring nightmares, can often signify underlying stress, anxiety, or unresolved issues in your waking life. The imagery of scary faces and frightening scenarios might reflect feelings of fear, helplessness, or anxiety that you may be experiencing in your daily life.

Here are a few insights and suggestions that might help you:

1. Journaling: Keep a dream journal where you write down your nightmares immediately upon waking. This can help you identify patterns or triggers that might be contributing to your distress.
2. Visualization Techniques: Before you sleep, try visualizing a peaceful scene or a protective figure that can help counteract the fear. This can create a more positive mindset before falling asleep.
3. Grounding Exercises: Practice grounding techniques during the day to help manage anxiety. Breathing exercises or mindfulness meditation can be effective in reducing overall stress.
4. Professional Support: Since you've already sought help from psychologists and psychiatrists, consider looking for a specialist in trauma or sleep disorders. Therapies such as Cognitive Behavioral Therapy for Insomnia (CBT-I) or Eye Movement Desensitization and Reprocessing (EMDR) might be beneficial.
5. Sleep Hygiene: Continue to maintain good sleep hygiene. This includes having a regular sleep schedule, creating a calming bedtime routine, and ensuring your sleep environment is comfortable and free of disturbances.
6. Support Groups: Sometimes sharing experiences with others who have similar issues can be comforting. Look for support groups where you can discuss your experiences.

Finding peace in your sleep is a journey, and it may take time to discover what works best for you. Don't hesitate to reach out for continued support as you navigate this process.
