I have written poems and music in my dreams (I've woken up with a poem or a melody in my head that I then have written down and/or transcribed, but I don't remember reading in dreams).
I have never felt pain in my dreams, but it does seem that my emotions are heightened in my dreams. For instance, about a week ago I had a dream in which I reentered the basement of a house I'd once lived in and it had flooded and clothes my children had worn and toys they'd played with as babies were floating around the basement and I woke up feeling unutterably sad, not crying but just sadder than I would have when awake.
And then a couple of days ago I had a dream that I was babysitting and I was swinging with this little girl on a swing and I woke up incredibly happy - just from swinging on a swing. I don't know how to explain it - it's like when I'm awake I'm working through the event logically and my brain is handling it and keeping my emotions in check but when I'm dreaming it's all feeling and emotion - so it's intensified.
I've also felt physical pleasure
(I don't want to get specific) in my dreams.
I also dream in color. Red is a very commonly recurring color (theme) in my dreams and always has been.
I almost always know the people in my dreams.
I seem to have my most vivid dreams just before I wake up and I can't control them - sometimes I've been enjoying a dream so much I try to reenter it after waking and I've never been able to.
