Why We Hallucinate Before Sleep: A Psychologist Unpacks ‘Hypnagogia’

Research reveals that hallucination just before or after sleep is a common occurrence, and it might Have you ever had the jarringly realistic feeling, just before falling asleep, that you’re falling through mid-air, leading you to jerk awake? Or perhaps you’ve felt this falling sensation just before waking up after a night’s sleep? If you’ve felt this before, you are one of many—approximately 70% of the population experiences this phenomenon. This is referred to as a “hypnic jerk,” and it’s the result of a broader, more intriguing phenomenon known as “hypnagogia”—the transitional state between sleep and wakefulness, which often entails the experience of strange hallucinations. For a long time, the causes, mechanics and effects of hypnagogia were relatively understudied, and the phenomenon still leaves psychologists and neurologists mystified.

However, progress has revealed new insights on the perplexing features of this hallucinatory state. What Is Hypnagogia? Many academics have attempted to unveil the mechanisms of hypnagogia. One describes hypnagogia as a normal and healthy state of consciousness that all individuals regularly enter between sleep and wakefulness, characterized by simple shifts in cognitive functioning.

This transitional state is entered in both sleep onset and offset, as we are about to fall asleep and as we are about to wake up. These shifts in cognitive functioning between states of wakefulness are understood to result in fleeting perceptual experiences, or “hypnagogic hallucinations,” that are spontaneous, involuntary and of varying levels of intensity. According to the study, approximately 85% of these hallucinations are visual, approximately 35% evoke physical, somatic sensations within the body and around 20% are auditory.

Importantly, these hypnagogic hallucinations are not the same as other common sleep-related perceptions. Specifically, hypnagogia is not the same as , parasomnia or sleep paralysis; hypnagogia is an entirely separate, and normal, form of hallucination. While the idea that up to 70% of the population spends their mornings or nights casually hallucinating might sound unbelievable, these fleeting perceptions are often common, simple and many don’t even realize that they experience it.

What Happens During Hypnagogia? According to published in the these distinct hallucinations vary in a multitude of ways, from frequency and sensation to precursors and effects: Who Is Prone To Hypnagogia? And Can It Be Induced? The aforementioned study highlights that certain individuals are more prone to experiencing hypnagogia, and the phenomenon is closely linked to sleep quality and various clinical conditions. Those with indicators of poor sleep quality as a result of insomnia, PTSD, depression or anxiety are more likely to encounter hypnagogic states. Interestingly, those with strong beliefs in were also found by the researchers to be more prone to hypnagogia.

Despite being linked to poor sleep and mood/anxiety disorders, hypnagogia offers a unique and beneficial realm for creative thinking and problem-solving. A published in the found that hypnagogia, allowing hallucinatory images to be critically examined while still before the eyes, is particularly effective in solving problems. The research highlights various historical figures, including August Kekulé, Beethoven, Salvador Dalí and Isaac Newton, who have credited hypnagogia as enhancing their creativity.

This suggests that the hypnagogic state provides a fertile ground for innovative insights and solutions that may not emerge in other stages of sleep, or even while awake. According to the study from the hypnagogia can be intentionally induced, with hypnosis emerging as a promising approach. The authors explain that the process involves 20-30 minutes of relaxing principal muscle groups, followed by 15-20 minutes of indirect hypnotic suggestion.

This intentional induction of hypnagogia not only adds an intriguing dimension to sleep research, but also presents an opportunity for individuals to explore their creative potential and problem-solving abilities in a controlled and intentional manner. The deliberate induction of hypnagogia could prove to be an interesting, maybe even fun, experiment, as well as a tool to harness the unique benefits this transitional state offers. Conclusion In the waning moments between wakefulness and sleep, hypnagogia unveils its mystique: a transitional state rich with strange hallucinations.

However, through intentional induction, hypnagogia may become a gateway to enhanced creativity and problem-solving. For those prone to it, or those curious enough to induce it, hypnagogia could be an intriguing avenue to explore the mind’s uncharted realms. .
