I dreamt that there was a floods all over the country and people were dying so the only safe place was at my ex place I went to my ex's house for safety and he welcomed me wholeheartedly but my ex's girlfriend was annoyed when she saw me
Dreams about floods often represent overwhelming emotions or situations in life. It's possible that this dream is reflecting your feelings of being overwhelmed or inundated with a crisis or problem that is affecting multiple people. The fact that you seek refuge at your ex's house may suggest that you subconsciously feel like you need to rely on someone from your past in order to feel safe and secure during times of crisis.
The way your ex welcomes you in the dream may indicate a desire for comfort and support during a difficult time. However, the negative reaction from his girlfriend may suggest a fear of conflict or confrontation that could arise as a result of relying on this person for help.
Overall, this dream may be signalling a need for support and safety during a potentially overwhelming time in your life, but also a fear of causing drama or conflict with people who hold emotional significance in your past.
