Question

Quizplus · Accepted Answer

Since Alyssa has just entered stage 1 sleep, she is in a relatively light sleep state. A sudden loud crash is likely to wake her up from her sleep. The EEG may show a brief disturbance in brain activity, but this is unlikely to be significant enough to result in a flat line or sleep spindle. The noise of the crash may be incorporated into a dream if Alyssa is able to fall back asleep quickly after being startled.
