I was in the old apartment I grew up in and it was night time. An old rotary phone rang and I sit down to answer it. It was on a table against the wall by the dining room and living room against the wall. My mother was on the line and we were talking. I told her she had passed away and she didn't know that. I asked her if she would continue to call me and she said she would. My sister was in a bedroom down the hall and after we hung up she came down the hall and I told her who I had been talking to
This dream could represent unresolved emotions and a desire to reconnect with your mother who has passed away. The old apartment you grew up in and the rotary phone may symbolize a sense of nostalgia for a simpler and more innocent time. The fact that your mother did not know she had passed away in the dream suggests that you may feel there were things left unsaid or unresolved between you and your mother. The phone call may represent a desire to reach out and connect with her, even though she has passed away.
The fact that your sister is also present in the dream may suggest a need for support and communication with your family members as you work through your feelings of loss and grief. It is possible that the dream is a message from your subconscious that it is okay to reach out to others and share your feelings about your mother's passing.
