I’m open to correction but my understanding is everyone dreams when they have REM sleep and everyone has some REM sleep every night unless there are rare medical conditions which would be unhealthy if there is a long period of no REM sleep.
People who believe they never dream (including myself before I learned this) simply don’t remember it. If you were woken artificially during REM you might remember fragments.
