Dreams involving ex-partners can often reflect unresolved feelings or lingering thoughts about the relationship. The transformation of your ex-girlfriend into a demon may symbolize inner fears or anxieties associated with intimacy or past experiences. This could indicate a struggle with your emotions or a fear of losing control in relationships.

Sleep paralysis, which you experienced upon waking, can be a frightening experience and may be linked to stress or anxiety. It’s possible that the dream and the sleep paralysis are connected; the intense emotions from the dream could have contributed to the sleep paralysis.

Consider reflecting on your feelings about your past relationship and what the demon might represent for you. Are there unresolved issues or fears that need addressing? Engaging in self-reflection or speaking with someone about these feelings may help you gain clarity and peace of mind.
