Is it normal to never have a nightmare?
Yep.Totally normal
Yes, it’s normal to never have nightmares—or to rarely remember having them. People vary a lot in what they dream about and what they recall after waking.
Some people have nightmares now and then, while others almost never do. You may still dream without remembering it, and stressful or scary dreams don’t happen to everyone.
If you’re sleeping well and feel rested, not having nightmares is nothing to worry about. Your sleeping brain isn’t required to produce a horror movie.
