![]() ![]() Certain medications, drugs, and alcohol can make these hallucinations more likely to occur, too, she adds. Or, according to sleep specialist Angela Holliday-Bell, MD, it could be tied to a condition like insomnia or mood disorders like depression or bipolar disorder. That could be something as seemingly innocuous as struggling to fall asleep (perhaps due to stress or anxiety), having an irregular sleep schedule, or pulling an all-nighter. More generally, anything that throws off the pattern of your circadian rhythm (aka your body’s 24-hour sleep-wake cycle) can also be a culprit. Varga, “but in some conditions, namely narcolepsy, that transition can be much faster.” ![]() “Normal physiology is such that REM sleep should take 60 to 120 minutes to occur from sleep onset,” says Dr. One explanation is that they may occur more frequently in folks who experience a quicker dive right into REM sleep (aka dream sleep), shuttling through the earlier stages of sleep too hastily. Vivid nightime visions during your sleep may be whats known as hypnagogic hallucinations, which are among the most common narcolepsy symptoms. The short answer: Science doesn’t fully know yet why certain people tend to get them (or get them more often), and others don’t. ![]() And it gets its name from the transitional state of consciousness in which it happens, called hypnagogia. Varga, MD, a physician at the Mount Sinai Integrative Sleep Center. Varga, MD, neuroscientistĮntirely distinct from a substance-related hallucination or a hallucination tied to a mental-health condition, a hypnagogic hallucination “occurs in the transition from wakefulness to sleep, either right at the time of initially falling asleep or in the middle of the night, if you’re briefly roused from sleep,” says neuroscientist Andrew W. “A hypnagogic hallucination occurs in the transition from wakefulness to sleep, either at the time of falling asleep or in the middle of the night, if you’re roused from sleep.” -Andrew W. “People occasionally feel as if something is touching them, or they could have a physical sensation like floating or falling.” Certain street drugs, like ecstasy and LSD, can make you see and hear things that aren’t there.

Hearing voices speaking when there is no-one there is known as an auditory hallucination. Hallucinations Associated With Mental Health. They both likely originate during an early, non-REM sleep stage. In 2000, another team of researchers surveyed 13,057 people and found that 38.7 had experienced hallucinations at some point during the day or night. And 12.5 had experienced hypnopompic hallucinations. Together, hypnagogic and hypnopompic hallucinations are referred to as hypnagogia. They found that 37 had experienced hypnagogic hallucinations. Despite how bizarre this scenario might appear, hypnagogic hallucinations of some sort are estimated to occur in as much as 37 percent of the population and are typically not something to worry about (more on that below). Hypnopompic hallucinations occur while a person is waking up, and hypnagogic hallucinations occur while falling asleep. ![]()
