Does this chart accurately illustrate the REM periods that you will have during the day as well (for example, during naps), or will they be different then?
That char says during 8 hours of sleep. I believe that the REM stages are different for everyone. No one really sleeps 8 hours a day. So it would also depend on the persons normal sleep pattern, the amount of time they sleep, and when they sleep. I don’t believe that any chat could accurately illustrate the REM periods. Unless you, of course, go get a sleep study done where they can measure it for that night (but then it might be different the next, so meh).
