I was followed by a little girl in my old house
Dreams can hold different meanings for each individual, but generally, being followed in a dream can symbolize unresolved issues or emotions that are "following" you in your waking life. The fact that it took place in your old house may suggest that these issues or emotions are connected to your past.
The presence of a little girl can represent innocence, vulnerability, or aspects of your own inner child. It may indicate a need to reconnect with your own youthful spirit or deal with certain unresolved childhood experiences.
Overall, this dream could be suggesting that there are unresolved issues or emotions from your past that are still following you and need to be addressed. It could be beneficial to reflect on your past experiences, emotions, or relationships to determine if there are any aspects that still require healing or closure.
