A Freudian would argue that your dream is about your fear that you lack personal agency. Finding something that matters to you that you can control, that you feel responsible for, that you have the ability to influence could potentially reduce the stress in your life. Not talkin' running for office, talkin' like a window garden. The dead kid could go a few ways.
There is no correlation between "when you dream" and "what instigated the dream". Dream state has a lot more to do with stress levels, sleep time, emotional state, what cheese you had before bed, etc. Oh yes I did. I did just totally link to an Erowid trip report on Stilton.
The description of that cheese actually sounds really good but 14 year old me would have glossed right over that and just headed to the store to buy tons. I was pretty angry at the other drivers after I loaded my groceries onto my mattress and just tried to get home so maybe it was bottled up stress.
