Dreams involving children often symbolize innocence, vulnerability, or aspects of ourselves that we are nurturing. In your dream, your neighbor asking you to help with her children may reflect a sense of responsibility or obligation you feel towards others in your life. It could also signify your willingness to help and support those around you.

The little boy's disappearance in the dream could signify a fear of losing touch with something important, whether it be your own childhood, innocence, or a relationship. It might also indicate anxiety about your responsibilities or concerns about not being able to protect those you care for. The note you found could represent feelings of guilt or self-doubt, particularly regarding the role you play in others' lives.

The reference to reading tarot cards could symbolize a quest for understanding or insight into a situation. It may suggest that you feel judged or misunderstood by others for your beliefs or choices, particularly in how you approach life’s uncertainties.

Overall, this dream could be prompting you to reflect on your responsibilities, the balance between helping others and taking care of yourself, and any feelings of inadequacy you might be experiencing. It may be beneficial to consider how you can address these feelings in your waking life and communicate openly with those around you.
