Weird dreams about work

Given that things have just been WEIRD and UNSETTLING recently, I guess it's no wonder that I'm having trouble sleeping. My dreams have morphed with people from my current life, to scenarios from my previous life... putting, say, people I work with now into the situation where I was working or living ten or more years ago. THAT's strange. I'm sure a lot of this is simply because I spend so much time with coworkers, that they'd naturally appear in my dreams (and at least they're not nightmares!)
