Dreams involving deceased loved ones can be deeply emotional and can reflect your feelings of loss, longing, or unresolved questions. In your dream, asking your mum about her well-being and her response about taking paracetamol may symbolize your concern for her peace and happiness after her passing.
The reference to paracetamol might indicate a desire for relief or comfort, either for her or for yourself. It could suggest that you're processing your grief and seeking ways to cope with the loss. Additionally, the silence when you asked if she was happy could reflect your own uncertainty about her state and your wish for reassurance.
Consider reflecting on the emotions you felt during the dream and how they relate to your waking life. It might be beneficial to talk about these feelings with someone you trust or to explore ways to honor her memory in your daily life. Remember, dreams can be a way for your subconscious to communicate your feelings and desires.
