Yup, and there are what is called vivid dreaming, and “double nightmares” where you think you have awakened from a bad dream, only to discover that you are still in the nightmare. Happens more when a person is sick, usually with fever. Can happen in stressful situations too. Especially the vivid dreaming where it seems real and is hard to tell the difference when you awaken. I’ve had a few of both type of dreams over the years. Hate hate hate the double nightmares! I think too that having watched horror movies might have contributed to such dreaming- like nightmare on elm Street where they were afraid to go to sleep for fear of meeting freddy- I think movies like that can influence the mind when dreaming, especially in stressful situations or when sick and feverish
LOL! No wonder I learned to play the accordion instead of guitar.
