Sometimes they even get out of bed and rush across the room and blindly strike the wall. Night terrors come from very deep sleep and are considered partial arousal phenomena. So people who experience night terrors are difficult to arouse and usually are not aware of having had an episode. Narcolepsy is a condition where people lose control of their sleep and of their dream sleep. They often sleep at inappropriate times and sleep much longer than normal.
Some narcoleptics can fall asleep while chewing food or standing in line and sometimes during sex.
They often suffer from other associated conditions related to their dream sleep. They may awaken totally paralyzed. They may experience dreams while awake that appear to them like hallucinations, and they may have what is called cataplexy, which is becoming weak or even paralyzed as a response to an emotion such as laughing or becoming angry. Sometimes people will wake up in the middle of a nightmare and feel very frightened. But night terrors are not associated with dreams usually.
