Actions and situations
Dreaming about killing
Dreaming about killing is traditionally read as not violence but removal — the dream usually concerns ending something and the guilt of wanting it ended. No survey has measured how often this one occurs, so we give the reading without a frequency — only 19 of the dream themes here have a published figure at all.
The psychological reading
The victim is frequently unknown, which supports the reading that the act matters more than the target. Where the victim is known, waking conflict with that person is usually present.
When it turns up
Why this dream arrives when it does
Killing dreams are about removal rather than violence: ending a role, cutting someone off, stopping something that has been going on too long. About a quarter of people report them, and men report them substantially more often than women in the standard survey.

The version matters
Different ways this dream shows up
The version carries most of the information.
Killing in self-defence and killing deliberately are separate readings; the second is rarer and reported as far more disturbing on waking.
Killing someone you do not recognise
The most common form, and the act matters more than the target. It follows decisions to end something, usually made and not yet acted on.
Killing someone you know
Far more disturbing on waking and usually connected to real conflict with that person. It does not indicate any wish to harm them, and treating it as one is the standard error here.
Killing in self-defence
A separate reading: boundaries rather than removal. Dreamers report it as justified and rarely feel guilt afterwards.
Killing an animal
The snake version is the most searched. It tends to accompany confronting something you had been avoiding rather than destroying anything.
Hiding a body
The aftermath dream, and the one people report as endless. It tracks consequences of an ending you have not admitted to — a resignation kept quiet, a relationship already over in your head.
Watching someone else kill
Places you as witness to a removal being carried out by others: a sacking, a family exclusion, a decision taken above your level.
Commonly claimed, and wrong
What this dream does not mean
These dreams are not evidence of violent urges, and no research links them to violent behaviour. Reading them as confession is what makes people hide them, which is also why the dream is discussed far less than its frequency deserves.

Questions about this dream
What does it mean to dream about killing someone?
Usually ending something rather than harming anyone — a role, a habit, a relationship. About one person in four reports the theme.
Is it bad to dream about killing someone I know?
It is uncomfortable, not diagnostic. It commonly follows unresolved conflict with that person and says nothing about what you want to happen to them.
What does killing a snake in a dream mean?
Most often confronting something that had been avoided. Dreamers usually report it after a decision rather than before one.
