I think the new job is probably a factor. Change is unsettling, even when it's good change, and it often triggers vivid dreams. I did my first ever solo wild camp a few days ago. I slept quite well, but I had a really weird dream that I opened my tent and a small animal rushed in and started biting me!
I went through a phase of reading dream interpretation books. Then I realised that the interpretations always varied wildly from book to book. Maybe the authors believe they are true. I don't know.
