Brian's Journal - A Dream Return

New job (12/15/2020)
I am on the first day of a new job, managing or operating a production line in a chemical plant. A coworker named Dan or John is showing me around a large high-ceilinged room filled with machines and tanks connected by pale yellow and-or pink plastic tubing. The process appears to start with a big jug of carpenters glue but that's about all I understand about it. My coworker leaves and I am not sure if I should go ahead and run the process or not so I go upstairs to ask my boss.
I am in his office when he comes in, a somewhat stout middle-aged man dressed in a blue-gray suit. Startled, he admonishes me to only approach him when he can see me first, but then he backs off and tells me it's okay. My coworker comes in and tells him that I learn quickly and will be very good at the job. I am pleased to hear that but I am also somewhat uncertain as to whether I want the job or not. Regarding my question, my boss explains that they are not ready to receive the product of my production line so I don't need to work anymore on it today.
I am sitting at a big desk in my otherwise empty office. The top of my desk is crowded with boxes of files and other belongings, some personal and some from my previous job. I wonder what to do for the rest of the workday and decided to look online to learn more about my product, so I clear a space on the desk for my keyboard. The surface of the desk is very dusty in the gaps between the boxes. A woman dressed in a bright red dress comes in with a spray bottle and rag and briskly offers to clean the dust off my desk. Sarah talks to her and explains to me something about "Lumpus", from which I infer that perhaps the woman has lupus. I noticed a shoebox in front of me filled with old typewritten and handwritten letters and I turn to Doug Reusch on my right and tell him "Hey Doug, Here's a letter I wrote to you back in the 60s, or maybe even '59." I speak loudly, so the woman in red can hear me.
Chemistry fascinated me when I was in junior high school. Doug shared that interest; it was Doug's dad who taught us to make firecrackers with our homemade gunpowder using a bit of iron picture wire for a battery-operated trigger. The boss in the dream reminds me of a teacher in high school, where taking classes in chemistry eventually dampened my enthusiasm for the subject. Chemistry, though, may not be the focus of the new job. The boxes of stuff on my desk, particularly the old letters, and the coworker in the red dress provide clues to the nature of the actual new job. For the past several months my focus has been on creating a timeline of my life with particular focus on the first 30 years, using old letters and photos to figure out what happened when and why I made the choices I did. The woman with the spray bottle and rag is Darchelle. Sarah's presence may serve to emphasize the focus on my childhood, the only period of our lives where we actually lived together. Like my timeline project, the dream links that childhood with the present in a single story.
