My dreams have been VERY weird and vivid too. I was stuck in a LARP game loop or something last night. .. and it was pretty violent/gory, weird. Eventually I basically woke my self up so I could 'switch channels'
I've also had the stuffing my face dreams a few times.
Weird stuff.
I'm not back on my vitamins yet, but when I get there, the B's are definitely happening in the AM!
