This statement is true. During REM (rapid eye movement) sleep, the brain is highly active and the body experiences physiological changes similar to those of wakefulness, including increased heart rate, respiratory rate, and blood pressure. This is believed to be related to the vivid and often emotional dreams that occur during this stage of sleep.
