Your brother's electric shock shows that he is in good health and full of energy now. Then you saw your brother die, which shows that you usually miss him and care about him. Then you burn paper for him, indicating that you want him to have a future and success when he grows up. When you burn paper, the fire goes out several times, which means that you will help him many times for his future success, and your burning and bubble green show that his success has a great reward for you. It's a good dream, don't worry.
As the saying goes, dreams are the opposite, so don't care too much, and don't affect your study and work because of dreams.
It's inconvenient to type on a mobile phone, so I can only tell you generously. I hope it helps you, and I wish you good luck.
