If I ever have a nightmare, that signals me that I'm not getting enough of certain hormone balancers.

I had a dream that actually came true. I dreamed that an idiot asshole because president.

Seriously though...... night before last I dreamed I was in a hotel room with an old woman. She was taking a bath, and the phone rang. I answered, and a man said he was coming over. I told him he had the wrong number and hung up. A few seconds later I feel a tap on my shoulder and the same voice said "I'm here". I woke up immediately, and didn't go back to sleep for hours.

I have a lot of dreams every night, and some of them are negative, and some are positive. Quite often something triggers and I realize I'm dreaming while in the dream and that's a lot of fun because I become all-powerful for about five or ten minutes. But to answer your question, yes I have "bad dreams," but I don't use the word nightmare because to me that implies boogyman type dreams and they're not that. My bad dreams are like falling off a cliff, or living with my x-wife (not joking) or being shackled to a young earth creationist. (not kidding, an actual dream I had)

Night terrors. Yeah. Frequently.

I dream often, have repetitive and serial dreams, with nightmare events occasionally remembering them.

Not often. Maybe if I have the flu. Or a bad taco.

Mine are like I'm on a toll road and when I get to the booth, I have no money and on and on where I can't get where I need to be. Another one is that I'm in college and find out during the last week of the semester that I was enrolled in some class and had never gone and then had to make it all up and take an exam that week.

After 911 I did for many years, I think it has not happened in about 3 years. I’m from Staten Island, watched the buildings go up, lost friends and all of my friends lost friends. The surveys never seem to include my answer. Took 3 days to get an email response from my best friend who was a fireman on the pile, all he wrote was, “It’s hell, Joe is dead”. Can’t even type that without it flooding back.

I don't remember my dreams - and I'm okay with that. That means no bad ones.

As a child, I had recurring nightmares that were like a Salvador Dali painting. After my divorce from my first wife (who had borderline personality disorder and made life miserable), I had nightmares involving her for almost 20 years.

I used to have very vivid dreams and nightmares in color every night, not so much any more. But I still have dreams that carry the same theme and occasional nightmares.

I still have dreams about, or related to when my father beat me as a child. Dreams of helplessness to defend myself are bad, but the ones where I’m unable to help my friends a family are worse.

I used to occasionally, but not had one since becoming an atheist about 17 years ago. I think dreams reflect our fears and aspirations, (as well as other emotions). Atheism released a lot of fears in my mind, I may get the odd 'bad' dream, like someone vandalising my motorbike. but that is the worst they get. The good dreams/fantasies have got better over time.
PS I couldn't vote, since there wasn't an option for 'Used to'.

Rarely.

I can't share the article from a paid CME site but nightmares are common across the lifespan and occur more commonly with stress. THey are only considered to be pathological if they interfere with a person's function

Now that I think about it... my nightmares ended when I gave up trying to be religious like my family and parents.

I need to write them down or tell them into a tape recorder. Steven King has written a lot of his works based on his nightmares. If you want to induce nightmares sleep in a cold room.

If you call conflict dreams nightmares?

Haven't had the waking up screaming my lungs out because there were strangers in the bedroom one since my ex-husband left (yes for real) but normal garden variety ones still (usually some dark distortion of reality). Think there is a recurring them here, except when I'm running a fever my nightmares are always about the parts of my life I need to do something about (as if I need reminding.)

Depends on how you describe a nightmare, never had a night terror but most of what I'd call nightmarish are more creepy than frightening or a feeling of falling out of control as I'm not comfortable with heights

Used to be a licensed electrician, I would have nightmares about wiring a new home and the drywall would be in place before I could wire the house.

I DO have nightmares ocassionally. They usually revolve around my mother's stroke and subsequent death. Go figure.

They are not nightmares anymore, more like Horror aventure stories that my mind makes up XD

I used to have nightmares. Not exactly so anymore. First, try to remember your dreams the minute you wake up. Write them down then or you will forget later. Today if I have a nightmare it involves saving someone from something, or things that might have been. Often some of this is mixed with final thoughts at bedtime and things going on in your life right now. What you end up with is disquised versions of anxiety mixed with hope and doubts. Very often you can interpret your own dreams this way. Not much in these dreams is really real in a valid sense.

One of my dreams involved driving. I drive for a living and used to do that years before also. I like driving. In this dream I was driving but the situation was different. My ex wife was in the dream and all of us (even others) were trying to keep dry. The dream was weird but I woke up to rain outside that you could hear on my rooftop.
Remember also that some dreams might be started by that last minute ham sandwich!
