ANY cheese after early evening gives me bad dreams/nightmares, learned a long timeago to not to risk it, and yes, they do seem SO real.
when in living in Scotland we had a lean-to against the house where we kept the wood for the fire, when I went to get some to break it up, it was alive with earwigs. after that I woke up hitting the pillow which I could see earwigs all over it - in the pitch black night? bad dream. (that was over 30 years ago and I still remember it vividly)
