Does diet coke give you nightmares?

I was a very religious water drinker. I enjoyed the zero calorie liquid. Then, I discovered Diet Coke, Coke Zero and Diet Cherry Coke. And since then have drank them by the liter for the taste and calorie lack.

But for some reason, as the days rolled onwards, I find my dreams becoming more vivid. As even longer stretches of time pass, I begin to have very realistic nightmares. It got to the point where I would wake up screaming in my sleep, or wake up many time in the night scared or confused at to what was real life or not. Paired with my normal imagination, my case might be more extreme then yours. But as far as I can tell from my many other friends and sister who drink Diet Soda, that this is not common.
