I can't say I have nightmares really... A nightmare for me is like if there's a food or drink I was craving before I fell asleep, I'll dream that I acquired that food or drink, by winning a game against one of my old teachers or something, and right before I'm about to take a bite or drink, I wake up and realize I never got that food or drink!
Do you have recurring nightmares of the same thing or different everytime?
