I don't remember anything, even after being awoken and asked if I was dreaming. I thought the screaming could be from my arthritis pain. Night terrors are a second cousin to sleep walking. A person will usually sit up in bed open their eyes and begin screaming. 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.
