As it sounds, arousal is when a person becomes 'aroused' or more alert to some extent during the sleep cycle. It is a change in brain wave activity. It does not necessarily mean waking up, but could just mean a shift out of extremely deep sleep to lighter sleep, from which it is easier to be woken up from.

What is pink noise?

Nystagmus is typically caused by brain injuries and is a result of brain damage. This eye condition may be referred to as “dancing eyes” because of the repetitive eye movement.
