Is it normal to not dream?
Mostly.Normal for most people
Yes—it's normal not to remember your dreams. You may still dream; most people simply forget them soon after waking.
Dreams tend to fade fast, especially if you wake up at a different point in your sleep cycle or get moving right away. Some people remember them often, while others rarely remember any at all.
Not recalling dreams by itself usually doesn’t mean anything is wrong. If you’re sleeping reasonably well and feel okay during the day, there’s generally no need to worry about your dreamless nights.
