Hi, welcome to the forum. Your history is suggestive of narcolepsy. In this condition there will be excessive daytime sleepiness. In this condition there will be “automatic behavior" such as driving past a highway exit or writing off a page, with no memory of the previous few minutes. Classical narcolepsy constitutes of Hypnagogic hallucinations, Sleep paralysis and Cataplexy (emotionally triggered muscle paralysis resulting in partial or complete collapse).
You need to undergo tests like Polysomnography, Multiple Sleep Latency Test and CSF levels of Orexin/Hypocretin which help to substantiate the diagnosis.
Having regular nap for about 20 min during day will help to prevent sleep attacks.
Drugs like Modafinil, Methylphenidate and Amphetamines against prescription can help to increase the alertness during the day and they are esp. useful in excessive daytime sleepiness or increased sleep attack.
You should try to have good sleep of 8-9 hrs in night so that you remain fresh in daytime. You can try coffee, tea which will make you remain fresh.
I suggest her to go for the further tests. Take care and regards.
