Red sky at night, Sailor's delight

Nightmare on Friday night. I woke up w/ a start. It was a strange dream and thinking about the previous day's events it finally occurred to me a seemingly innocuous comment that probably triggered it. Once I determined the cause, I fell peacefully asleep until morning. Last night, another nightmare. No idea what caused this one and I fell asleep again - only to wake up again when it reoccurred. I got on-line to see what causes nightmares and one of the reasons is eating fatty foods.  Who would have guessed mac & cheese could be so terrifying?
