What it means
Peace is one of the kindest things a night can leave you with. It comes in open landscapes, still water, soft light or silence, or in encounters with people you love. The hallmark is that nothing needs to happen: just being there is enough.
Maybe the dream reflects a conflict that's winding down: a decision made, a grief that's softening, a relationship that found its footing. Or it may show you the opposite of what you're living: if your days are full of noise, your mind offers you somewhere to rest.
It's worth writing down what was in that scene. A place, a person, an activity: those details are often clues to what brings you calm during the day as well.
Common variations
Peace for no reason
A lake, a meadow, an empty beach, and a deep calm settling into your body. Nothing happens and everything is fine. Sometimes something has resolved inside before you've noticed it by day, or when you need a pause. You can return to that image when sleep won't come.
Peace beside someone who died
A loved one who passed away appears calm, smiles or hugs you, and leaves you at peace. Many grieving people experience this dream as a missing goodbye, or as a sign that something can be let go. Take it as comfort, without needing to read more into it.
Making peace with someone
A reconciliation with your ex, a relative or a friend you fell out with. It may show you're ready to let the anger go, or that you wish the relationship could heal. The dream doesn't guarantee it will happen, but it shows you how it would feel.
Peace in the middle of chaos
Around you there's a storm, a fire or people running, and you feel a strange calm. It often speaks of an inner strength you don't always recognize, or of some distance from a problem that no longer scares you the way it used to.
Wanting to be left in peace
You shout "leave me alone," shut yourself in, or pull away from someone who won't stop asking things of you. Here peace is what's missing. It usually signals exhaustion, too many demands or the need for a boundary. Ask yourself who or what is stealing your rest.
What psychology says
Els van der Helm, Matthew Walker and colleagues (2011) showed volunteers emotional images twice, twelve hours apart. Those who slept between the two sessions reacted less strongly than those who stayed awake through the day, and that easing was tied to brain activity during REM sleep. Sleep seems to dull the emotional edge of what you've lived. The peace a dream sometimes brings may be part of that work.
In folklore
The dove carrying an olive leaf comes from the biblical flood story, and "rest in peace" renders the Latin requiescat in pace, still carved on many graves as RIP. Some people take a peaceful dream as a sign of good fortune. There's no need: the dream already did its job by leaving you calm.
