In the dream I was washing my mouth with mouthwash, and once I finished with the mouthwash, I started spitting it out. Well, I spit about 10 times into the sink in the dream, but not only did I spit in the dream, I also spit on my pillow in real life 10 times. I know this because I woke up right as I was spitting the 10th time so I caught myself in the act. I felt the rest of my pillow and it was soaked with my spit, it wasn't the best feeling ever.
That being said, I think at times its possible, but it all depends on the person and some other factors.
