I saw my ex/boyfriend in the dream sleeping facing the window as he always did. Then I saw him get up from the bed to leave the room and as he turned the corner of the bed he turned into a black mouse like rodent and he started charging my way and I got scared because I was on the floor hiding from him in the dream and I woke up.
Dreams involving ex-partners can often reflect unresolved feelings or thoughts about the relationship. In your dream, seeing your ex-boyfriend suggests that his presence is still significant in your mind, possibly indicating that you're processing past emotions related to him.
The transformation of your ex into a black mouse-like rodent could symbolize feelings of fear or anxiety related to the relationship or aspects of it that you may find unpleasant or untrustworthy. Mice often represent feelings of vulnerability, and in this case, your hiding on the floor suggests a feeling of powerlessness or a need to protect yourself from emotional threats.
The act of charging at you can signify a confrontation with a part of your past or a fear that is now manifesting in your subconscious. It may also reflect a fear of being overwhelmed by your emotions or memories associated with him.
Overall, this dream could indicate that there are lingering feelings or unresolved issues from your relationship that you need to confront. It might be a way for your subconscious to encourage you to address these feelings rather than hide from them. Consider reflecting on your current emotions regarding your ex and how they may be impacting your present life.
