Among 174 people who died prematurely, 31 experienced at least weekly nightmares. Otaiku's research shows chromosomes of nightmare-prone individuals display accelerated aging patterns linked to stress hormones, accounting for roughly 40% of their increased mortality risk. Effective nightmare treatment options are currently limited and require more medical research, the report adds.

I dream a lot lately, too. Mine are also in color. But mine, while they contain dreamlike elements, in that some stuff usually happens that doesn't quite make sense, they're generally about pretty ordinary situations, even if things like people and locations are made-up.
As for why I have frequent dreams, I just associate it with getting good, restful sleep.

That was a myth years back. There's no truth in it. Yes, people dream in color, not black and white.
The only explanation I've heard why this may have been true (or partly true) is that years ago movies, and television, was in black and white. Peoples' dreams echo the format of their entertainment, so if they watch movies in black and white, they (sometimes) dream in black and white.

The old adage, "correlation isn't necessary causation". People with PTSD are more likely to have nightmares, but the stress of PTSD itself shortens their life, nightmares probably being mostly a side-effect, not the cause.

So if you're relaxed about smoking, it won't kill you as fast as if you're stressed about human interaction to the point that it gives you frequent nightmares? In other words if smoking is your way to relieve stress, is it healthier to smoke than quit because doctors told you to, and be more stressed?

How would you possibly quantify the relative impact of either of those? :) But fun anecdote, my uncle was a lifetime smoker, started when he was probably 12 or 13. Once diagnosed with congestive heart failure his doctor told him to just keep smoking, as the stress from quitting would kill him sooner.

Since the summary does say "effective nightmare treatments are currently limited," I will go ahead and point out the correlation != causation thing. I would be very surprised if there weren't any other obvious causes of the nightmare that are known comorbidities, like poverty, or serious illness, or trauma, and so on.
For example, depression is associated with a 1.5x to 2.5x higher risk of early death, even when adjusting for other risk factors. The summary shows no sign of having adjusted for other risk factors, so 3x doesn't seem out of line.

> Effective nightmare treatment options are currently limited
This seems like backwards thinking. They link the aging and premature deaths to increased stress hormones and then seem to imply that the nightmares are the cause of this stress. However, given that stress can cause nightmares surely the most likely cause is some underlying stress and both the nightmares and premture deaths are symptoms of that? Instead of attempting to treat the nightmares they first need to show that there is no underlying cause of stress leading to both nightmares and aging because if there is some underlying cause of stress that's probably a lot easier to fix.

My favorite is how in some dreams it is easier to go backwards than forwards.

Yet turning around to face backwards and pushing off your toes oddly beats the effect or specifically using handrails to kinda pull yourself faster than walking goes.

I suffered from sleep apnea for many years. Breathing problems often triggered nightmares, several times a night. A CPAP machine changed my life, I could finally get a whole nights sleep, and the nightmares stopped. I can still recognize an apnea nightmare, which I get if I don't use the machine. Sleep apnea is known to increase many medical problems and to shorten life. I guess other conditions could also provoke nightmares.
