I'm in the midst of a 30 day Paleo challenge, and while sleeping I've been dreaming that I'm breaking my diet, either intentionally or by accident, e.g. I find some cake and I start eating it and realize halfway through that I shouldn't be eating it. Or I have dreams where I'm walking through a grocery store and can't find anything Paleo to eat or buy.
I'm pretty sure this is normal, but I'd be interested to hear if anyone else has these kinds of dreams.
