This dream contains a variety of vivid and complex symbols that may reflect your current emotional state, fears, and experiences. Here are some insights into the various elements of your dream:

1. Mosquito and Baby: The mosquito could symbolize something small that is bothering you or draining your energy. The idea of it laying something inside you that later appears as a dead ferret might represent feelings of being overwhelmed by something negative or unwanted in your life, which could be a burden or responsibility you feel is not thriving.
2. Grandma and Help: Your grandmother's refusal to help could indicate feelings of disappointment in seeking guidance or support from family. It may reflect a sense of isolation or the feeling that those who should care for you are not available.
3. Seeing Your Ribs and Bones: This imagery often symbolizes vulnerability or a sense of exposure. It could be a representation of feeling stripped down, either emotionally or physically, as if you are showing your true self to the world, which may feel fragile or lacking.
4. Heart and Breathing: Despite the alarming imagery of being just bones, your heart still beating suggests resilience. It reflects a strong will to survive and push through difficult situations, even if you feel empty or lacking in some aspects of your life.
5. The Inability to Call for Help: The struggle to dial 911 and the numbers changing to 411 may signify feelings of helplessness or frustration in trying to reach out for assistance. It may imply that you feel unheard or unseen by those around you when you need help the most.
6. Lack of Support: The absence of your mother and Pooh could highlight feelings of abandonment or neglect. You may be grappling with issues of support and care in your life, feeling as though those you rely on are not present when you need them.

Overall, this dream seems to express deep anxieties about vulnerability, the need for support, and the struggle to navigate through difficult emotional terrain. It may be helpful to reflect on your current life circumstances and consider discussing your feelings with someone you trust or a mental health professional. Understanding the sources of your stress and seeking support can lead to healing and clarity.
