dreamt i had a younger sister i had killed and that she was trying to hurt my family so i spoke to her everynight so she wouldn't feel lonely
Dreams can often be complex and have different interpretations depending on the individual's experiences and emotions. However, I can offer a possible interpretation for your dream.
Dreaming of having a younger sister whom you have killed may symbolize a sense of guilt or remorse, perhaps related to a past event or action. The fact that she is trying to hurt your family could represent the fear of repercussions or consequences for your actions affecting those you care about.
Speaking to her every night in order to alleviate her loneliness might indicate a desire for reconciliation and forgiveness. This dream may reflect your longing to make amends or find resolution for a past mistake or harmful behavior.
However, it's important to remember that dreams are highly personal, and only you can truly determine the specific meaning that resonates with you. If this dream continues to trouble you or have a significant impact on your emotions, it might be beneficial to explore it further with a therapist or counselor.
