Medical Daily discusses the research surrounding the question: Do we all have the ability to dream or are some of us non-dreamers in our sleep?
In many of these participants’ cases, however, their actions during sleep implied they were dreaming. For example, a 73-year-old participant claimed he used to recall dreams as a child but stopped at the age of 20. Meanwhile, in the sleep lab, he was talking, yelling, and moving his legs and arms, all while he was asleep. “[Videos show] the patient arguing, swearing profanities, kicking, boxing, and throwing items toward an invisible individual during REM sleep, as well as fighting again in another REM sleep episode one year after, with no subsequent dream recall despite the nurse’s immediate inquiry,” the authors wrote.
