There are times where I cannot distinguish a dream from reality. I am not a frequent dreamer, but then I do dream, it is hard to distinguish if I am awake or not. I can talk, move, or react to my dreams and then waking myself up in a sea of confusion. I wake up anxious, and scared if the dream was actually a nightmare. On rare occasions, I scream while asleep, and the sound of my voice wakes me up, adding more intensity to the inexplicable fear.
