Dreams involving death and funerals can often symbolize transformation, change, or the end of a particular phase in life. In your dream, the people who passed away transforming into balloons may represent the release of emotions or the idea of letting go of burdens. Balloons are often associated with celebration and freedom, suggesting that you might be processing feelings related to loss or change in a positive way.

Your feelings of peace and happiness while helping them could indicate a desire to support others or to find closure in your own life. The presence of your younger cousin, despite not being close, could symbolize family ties or connections that are present, even if they are not active in your life. It may suggest a reminder of family bonds and the importance of supporting one another during transitions.

Overall, this dream could be encouraging you to embrace change and to be open to helping others, whether they are close to you or not. It might also be a prompt to reflect on your own feelings about transformation in your life and how you can find peace in letting go of the past.
