Hypnagogia is the experience of the transitional states to and from sleep:


Sensory phenomena

Transition to and from sleep may be attended by a wide variety of sensory experiences. These can occur in any modality, individually or combined, and range from the vague and barely perceptible to vivid hallucinations.
Sights
Among the more commonly reported, and more thoroughly researched, sensory features of hypnagogia are phosphenes which can manifest as seemingly random speckles, lines or geometrical patterns, including form constants, or as figurative (representational) images. They may be monochromatic or richly colored, still or moving, flat or three-dimensional (offering an impression of perspective). Imagery representing movement through tunnels of light is also reported. Individual images are typically fleeting and given to very rapid changes. They are said to differ from dreams proper in that hypnagogic imagery is usually static and lacking in narrative content,[16] although others understand the state rather as a gradual transition from hypnagogia to fragmentary dreams,[24] i.e., from simple "eigenlicht" to whole imagined scenes. It has been claimed that hypnagogia can be induced with a Dreamachine,[25] which uses light pulsing at a frequency close to that of alpha waves to create this effect, but this claim has not been tested in scientific experiments. Descriptions of exceptionally vivid and elaborate hypnagogic visuals can be found in the work of Marie-Jean-Léon, Marquis d'Hervey de Saint Denys.


Tetris effect

People who have spent a long time at some repetitive activity before sleep, in particular one that is new to them, may find that it dominates their imagery as they grow drowsy, a tendency dubbed the Tetris effect. This effect has even been observed in amnesiacs who otherwise have no memory of the original activity. When the activity involves moving objects, as in the video game Tetris, the corresponding hypnagogic images tend to be perceived as moving. The Tetris effect is not confined to visual imagery, but can manifest in other modalities also. For example, Robert Stickgold recounts having experienced the touch of rocks while falling asleep after mountain climbing. This can also occur to people who have traveled on a small boat in rough seas, or have been swimming through waves, shortly before going to bed, and they feel the waves as they drift to sleep, or people who have spent the day skiing who continue to "feel snow" under their feet, also people who have spent considerable time jumping on a trampoline will find that they can feel the up-and-down motion before they go to sleep. Many chess players report[citation needed] the phenomenon of seeing the chess board and pieces during this state. New employees working stressful and demanding jobs often report doing work-related tasks in this period before sleep. This is very common[citation needed] amongst new waiters or waitresses in busy restaurants where they report having "Server Dreams" and restlessly wait tables in this state of mind, sometimes jolting them fully awake or preventing them from transitioning into actual sleep.

Sounds
Hypnagogic hallucinations are often auditory or have an auditory component. Like the visuals, hypnagogic sounds vary in intensity from faint impressions to loud noises, such as crashes and bangs (exploding head syndrome). People may imagine their own name called or a doorbell ringing. Snatches of imagined speech are common. While typically nonsensical and fragmented, these speech events can occasionally strike the individual as apt comments on—or summations of—their thoughts at the time. They often contain word play, neologisms and made-up names. Hypnagogic speech may manifest as the subject's own "inner voice", or as the voices of others: familiar people or strangers. More rarely, poetry or music is heard.

Sleep paralysis
Humming, roaring, hissing, rushing, zapping, and buzzing noises are frequent in conjunction with sleep paralysis (SP). This happens when the REM atonia sets in sooner than usual, before the person is fully asleep, or persists longer than usual, after the person has (in other respects) fully awoken. Sleep paralysis is reportedly very frequent among narcoleptics. It occurs frequently in about 6% of the rest of the population, and occurs occasionally in 60%.[28] In surveys from Canada, China, England, Japan and Nigeria, 20 to 60% of individuals reported having experienced SP at least once in their lifetime. The paralysis itself is frequently accompanied by additional phenomena. Typical examples include a feeling of being crushed or suffocated, electric "tingles" or "vibrations", imagined speech and other noises, the imagined presence of a visible or invisible entity, and sometimes intense emotion: fear or euphoria and orgasmic feelings. SP has been proposed as an explanation for at least some alien abduction experiences and shadow people hauntings.

Do any of you guys suffer from these hallucinations?

Originally posted by TSDMusicND Since the time I searched about sleep paralysis, I have been getting them A LOT But it usually happens when u are extremely tired. Then when you start having nightmares you have such an hard time to wake up cause you are sooo tired and your eyes won't open easily. then when you finally wake up, you kinda are still stuck in the dream so very akward stuff happens thanks to your own mind

my end is near ... bye

Sorry boo

But its normal because we start getting interested in the subject and then we think a lot about it and our mind goes cray cray.
Also if you are an horror fan like me, espect a lot of sleep paralysis as well
Since the day I saw that Squidward's Suicide awful picture that my mind as been a mess. Also is kinda funny that on that time, my brother and my mother were having those sleeps as well

Originally posted by evo While lying on my back I've had the paralysis, sights, and sound (only once for sound) phenomena. While laying on my front I've had the paralysis, sights. I've had the tetris once or twice, although I do not remember how I was sleeping those times.

Originally posted by RehabRihanna What a coincidence, this happened to me last night around 3am. I usually sleep on my side but I must have rolled onto my back during sleep. I woke up unexpectedly and I couldn't move my body. I felt something in front of my face and it was breathing really heavy and I felt loads of hands all over my body. This is the 4th time this has happened in the past 2 years but last night was the first time I actually hallucinated. I didn't go back to sleep for 2 hours, I was terrified.
