Final answer:
During REM sleep, our bodies experience temporary paralysis known as sleep paralysis to prevent us from acting out our dreams and potentially injuring ourselves.
Step-by-step explanation:
The statement is false. During REM (Rapid Eye Movement) sleep, our bodies experience a temporary paralysis known as sleep paralysis. This paralysis actually helps prevent us from acting out our dreams and potentially injuring ourselves. However, it lasts for a very short period, typically a few minutes, and not 2 hours as mentioned in the question. During the course of a night's sleep, we cycle through different stages of sleep, including REM sleep, multiple times.
