While asleep, we experience a period of REM sleep approximately every 90 minutes. It is during this time that we typically dream. These periods are initially very brief - only around 10 minutes. But as the night progresses, these periods become increasingly longer - often stretching to over 45 minutes at a time. Can somebody paraphrase this?

Answer and Explanation:

A paraphrase consists of rewording something that was said by someone else. That is, we say the exact same thing but with different words. Therefore, let's take the key information provided in the passage and rewrite them with our own words:

- Every hour and a half or so, while we sleep, we go through a period of REM sleep, which is when we usually dream. At the beginning, those periods last around ten minutes only. However, they keep on increasing throughout the night, reaching even the duration of 45 minutes.
