What are night terrors, and how do they differ from nightmares?
_Night terrors_ are episodes of intense fear, screaming, and thrashing that typically occur during the first few hours of sleep, often in the _deep non-REM sleep_ stages. Unlike nightmares, children experiencing night terrors usually do not remember the episode upon waking. Night terrors can be alarming for parents but are generally harmless and tend to resolve with age.
