So, I fell asleep rather late, getting consumed by a book I’m reading, I finally put it down, looked at the time (4:00am) and decided to go to sleep. I woke up abruptly, to an alarm I forgot to shut off that I use for work,(6:00am) today was my day off 
. So I went to write down the flurry of dreams I had, I must have had 4 or 5 because I wrote down so much and took up many pages of my Dream Journal. I went to look at the time. (6:42am) It took me 42 minutes to write all that? wow. then I realized after I woke up a little bit more. I had only been asleep for two hours! I couldnt have had so many dreams with such little time to go through REM could I? 
It was really cool nonetheless.
Well, actually Wuffles, most dreams only last a few seconds, they just feel long to us.
I can’t explain the REM, I know that it happens after 4-5 hours of sleep. Perhaps since you went to bed so late you entered REM sooner?
Most dreams are quite short; in fact, you can have several dreams in one REM cycle. The problem is recall. Seems to me like your recall was very good and allowed you to remember more dreams 
At first they’re in 15 second interals. Then as you go into REM more often during the night, you have longer REM cycles. Least thats what I have researched. But there was so many details that I couldn’t possibly think it was just a few seconds O.o…
Whatever the case, thanks for the replies
I had a few nights just like yours. Not important when I woke up but the amount of time I have slept, right? So just like in your case only a two hours or maybe a little bit more of sleep I woke up with so many things, scenes, fragments, feelings that I just didn’t know where to start! So I know the feeling, but why that happened I don’t know, but I assume from your case that the reason must be that you were reading for some good time before going to bed and that maybe helped to activate your brain more then it’s active usual before sleep and plus you being awake so long that maybe helped you to enter REM faster.
So higher brain activity + quicker REM entering = more dreams in shorter time. IMO!
Hmmm… interesting. I think I’ll use the brain activity to my advantage. I love reading, but I try not to do it too much because I get absolutely obsessed with it and thats all I want to do for some time. But when I do allow myself the obsession, I have dreams that are themed with the book which is odd, because no matter what happens in waking life, my dreams are never themed in the same way at all. I’ll start expermenting 
There’s the theory that if something out of ordinary happens to you trough the day, that you will dream about that, probably not exactly the same scene but something related to that. For example if you visit or you know you will visit some place that amaze you probably will dream about that and that you can use as a DS, and I even opened the topic about that. So in your case if you can really get obsessed with books and reading I assume that you can practically experience what you’re reading, right? [I meant in your head in your imagination] And then is no weird to dream about that and like I mentioned earlier you can use that as a DS!
As for as I’ve read that’s actually just a myth. Dreamtime isn’t all that different from realtime, but due to the constantly changing dreamscapes it looks like you can do a lot in a short time and also it makes it hard to estimate time.
I heard this too. 
That’s where the movie Inception was wrong too…
I stand corrected.
