Medical Do you dream constantly? Does dreamless sleep even exist?

Do you dream constantly? Does "dreamless sleep" even exist?

We know that...
We can dream in all 5 stages of sleep (not just REM)
We move around very often throughout the night (all in nREM since you're paralyzed in REM)
Memories are sorted out constantly in all stages of sleep.
And if you look at history of sleep "research"
First we thought that you dream once or twice every night and most of it is dreamless because we didn't remember dreams
Then that we dream throughout REM.
Then that most dreams are in REM and some in nREM.
I think that it's reasonable to say that you dream constantly and there is no "dreamless sleep"
Or if there is, it's almost certainly not a thoughtless void like most people imagine, and the thoughts in it are very similar to dream thoughts (perhaps not connected in a dream...?)

Also does that mean you dream when you're awake?

Have you looked online for any actual scientific research?

 

[CherokeeInjun]

Yes, that's what i got.

Yes, that's what i got.

Show me the sources please, links will be fine. Remember, they must be mainstream scientific studies.

Well one of the links I gave you is the memory activation theory.
The rest I found by google, so I can try to find them again.

That was deleted as an inappropriate source.

Thanks, I'm curious what you've been reading.

According to this (and other sources I forget) you dream in all stages.
Also why was that an inappropriate source?

That is also not a valid source, it's a student paper.

This is a valid source.

There are a few others (but none of them are .gov)
What exactly constitutes a "valid source"?
Just a .gov URL?

Also peer reviewed articles in an accepted journal found here http://science.thomsonreuters.com/mjl/. In some cases an article that cites studies found in such journals, as long as the article is accurate and isn't an opinion piece that deviates from the actual study's conclusions. Websites that contain well known and easily verifiable scientific information.

What we don't accept as sources are opinion pieces, speculation, personal theories, and anecdotes.

It's right that we have rumination during nREM - not vivid dreams but desultory thoughts.

This has been discussed before.
