What is the meaning in a dream of cart

Riding in a mine cart that crashed

I was watching a man film a birthday message for his son as he has cancer. Then I was with a group of people at a county fair watching horses and cows, there were food carts around me. The group walked through a crowd of people and came to en empty car park. The spaces were reserved for "(the year) 1946 enthusiasts and homeless people." We walked through the car park towards a dark building. I waved to my parents who were sitting at a table and continued on into the building. A young man walked past me and told his friends he would catch up, he had to do something first. I watched his eyes as he started watching the video message his father was recording at the start of my dream. At the end, I heard 3 loud pops and woke up knowing his father had shot himself as he was already dying

I was in the auditorium at Martha Brown. I was on stage, moving these set pieces over and over again trying to get them lined up perfectly. The set pieces felt larger than life, as the height was so great it was almost imperceptible-like a skyscraper. I was lining them up incorrectly- from the back instead of the front. I could feel myself getting anxious and overwhelmed. Then l, or someone else, took a photo of the audience and there was a big flash. After that, another person on the crew walked in carrying a cartoon-ish pillow I asked who made them and it was the person who was supposed to be my new boss. He carved them out of wood.
