I would be happy to help assist you in understanding your dream and your brother's dream. The plane crash and accident are symbolic. They represent a time in your life where your brother is going to have a dramatic impact in his life that will cause him to some issues. He may go through a period of change. Perhaps working through negative emotions or thoughts. He may also choose to make a wrong choice that will cause division and havoc in his life. So keep an eye on your brother, and make sure you are there to always support him and love him no matter what he is going through. If you have any more questions please feel free to ask.
