Dreaming and Remembering Them

Dreaming. Everyone does it. But not everyone remembers their dreams when they wake. I usually remember the last thing I dreamed and when I wake up I try to compose a tweet about the dream. Then I tweet it when I get on my computer, an hour later. Sometimes sooner.
If you follow me on twitter you'll see these rambling tweets. Or go over to #strangedreams It's mostly me and my dreams on that site.
Sometimes dreams leave me with an emotion I carry with me throughout the morning and that can really suck if the subject matter was scary or sad. I'm sure we've all woken up sad and wondered why. I love it when I have a happy dream and wake up happy, or excited about something, or wake up having just had a flying dream. These are my favorites and I have to wonder how I know what it feels like to fly.
But I do.
I have a very clear idea of what it feels like to be up that high and to glide over cities and water and bridges and trees. I wish I could dream of flying every night but I probably only have one of these a month. The feeling of flying is heady and wonderful, like scuba diving in some regards.

Dreams are still an enigma in this modern world. Scientists say it's our hind brain not shutting off when we sleep and feeding us images and ideas, like a pestering child. I prefer to think we actually visit alternate universes.We travel while we sleep.
I write books that always have the protagonist dreaming. Sometimes the heroine has a recurring dream. I have a novel series where the two main characters dream together and apparently this is possible. I had no idea when I started this series.
Dreams have always found their way into my books. Early on in my writing career, I heard that it's an author no no to start a novel with a dream. And to end the novel by saying the story was all a dream. Then I heard that people don't read books about dreams. I wasn't sure why but by the time I heard this advice I was too far gone and working on my next book about Dream Jumping, or sharing dreams. It's only been recently that I realized that the one thing all my novels have in common is dreaming. All the female protagonists are affected by their nightly dreams. Even the novel I'm releasing in the next few months, and doesn't have a thread of supernatural in it, has some strange dreams. Even my romantic suspense novel has the heroine dreaming about this and that. Mostly about the hunky, yet elusive neighbor. Because I remember dreams in the morning and because my husband calls out in his dreams nightly, I am affected greatly by my dream life.
The Dream Jumper Series has some weird-ass dreams and lots of information on lucid dreaming, Wake Induced Lucid Dreams and even ghosts entering dreams, which is something I think I made up until I hear from a reader that it's happened to them.

What about you? Do you dream? Ever had a lucid dream where you know you're dreaming?
