Is it normal to know you're dreaming?
Yep.Totally normal
Yes—knowing you’re dreaming while a dream is happening is normal. It’s called lucid dreaming, and it can happen occasionally or more often for some people.
That moment of “Wait, this is a dream” is called lucid dreaming. You might simply realize you’re dreaming, or you might also be able to influence what happens next; not everyone gets that much control.
It’s a familiar experience for lots of people, though how often it happens varies. On its own, it’s nothing to worry about—your brain is just having an unusually self-aware dream.
