What seemed like an eternity was probably a couple seconds. It felt like the covers were burying me, like I could barely breathe.

Hypnagogic/Hypnopompic Hallucinations character

Hypnagogic Hallucinations

Many people with narcolepsy have vivid dream-like experiences while falling asleep, called hypnagogic hallucinations. Hypnopompic hallucinations are similar experiences but they occur while waking up.

Sleep Paralysis character

Sleep Paralysis

Sleep paralysis is the inability to move or speak when falling asleep or waking up. The paralysis usually lasts a few minutes and ends suddenly or when someone touches the person. Hypnagogic hallucinations and sleep paralysis can occur in any sleep-deprived person, but their presence can help in recognizing narcolepsy.

Disrupted nighttime sleep character

Disrupted Nighttime Sleep

Some people living with narcolepsy have disrupted nighttime sleep and may wake up often throughout the night. The inability to sleep well at night is often reported by people living with narcolepsy as a significant lifestyle limitation and sometimes more of a problem than other symptoms.

Telling a healthcare provider about all signs and symptoms, even if they seem insignificant, is important. Find out how other people living with narcolepsy prepare for an appointment. »
