I was on a ship with my Mom and my family except my dad and she proposed to kill my brother. She was making me be the one to do it and i kept sobbing and i said i couldn’t do it so we’d have to just let him go and she agreed after i said he’s our family and she cried too. He began stealing from other places and then I was at a different school and we went on a field trip that was just a competition of opening up our mailboxes and it was so competitive people started crying. Afterwards they released mosquitoes and then we all ran away and it was a terrible field trip. Me and my friend held hands into the school and we didn’t know where to sit but it was okay.
Dreams are highly personal and can be interpreted in many ways. However, based on the information you provided, it seems that the dream might be a reflection of some underlying fears and conflicts in your family dynamics.
The proposal of killing your brother by your mother could symbolize an urge to get rid of some aspect of your brother's personality or behavior that you find challenging. The fact that you were reluctant to do it suggests that you don't want to hurt him and want to keep him close to you. This could reflect this feeling in your waking life.
The second part of the dream, where you compete with your friends in a field trip, shows that you have some competitive spirits that are driving you to perform better than others. The image of mosquitoes that were being released into the area could represent something that is coming from outside of your life and ruining your good efforts. It may be a symbol of external frustrations that are sabotaging your progress.
Overall, the dream could suggest that there are conflicting feelings within your family that could be causing you stress, and that you might have an underlying fear of losing control. Alternatively, it might be an expression of the competitive spirit that is driving you to succeed and excel.
