EDIT: Let's cool it with the downvotes, dudes. We're not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don't believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I'm sure almost everybody has something to add.

That’s interesting… because I always thought that REM sleep was the most important part of sleep, and more was better.

In fact, I read an article once that suggested that REM sleep was when our spinal fluid flushed all the waste material out of our brains at night (which leads to the types of dream that occur during REM sleep), which is also a process that prevents brains from being clogged with waste material.

I always thought that our brains being filled with waste material was part of depression, and that flushing out that waste material would help our brains function more correctly.

Sounds like the opposite - like, our depressed brains are depressed because they think too much?

Characteristic sleep-EEG changes in patients with depression include disinhibition of rapid eye movement (REM) sleep, changes of sleep continuity, and impaired non-REM sleep.

Yeah, I think we have multiple types of sleep because we need them, and if you're getting too much rem sleep at the expense of other types it's going to cause problems.
