I have lately been having the strangest dreams. I have heard (I don't know how true it is) that when you have a really deep sleep, you are more likely to dream. Anyway, I have been overloaded with stuff and work and more stuff, and I've been sleeping really deep sleeps. If I don't set my alarm clock, and I go to sleep at 8 or 9pm, I could sleep for 10 hours straight I'm so exhausted. Lately though, I have been having the strangest dreams, but I wake up thinking they are real. I thought I'd had a conversation with my sister and cancelled something, and it turned out I'd had a dream about the conversation and it hadn't happened.
The weirdest however, was about my teeth. I am going on Tuesday to have a wisdom tooth out. I didn't think I was worried about it, but I think my subconscious is telling me otherwise. I had a really indepth dream about my teeth all going really white at the roots, and when I pushed on the tooth it just caved over, and basically all my teeth fell out. I was so upset, I woke up in a panic and had to check all my teeth, it felt so life like!! Crazy!
A lot of authors (like J Ward) dreamt about their MC and so wrote a book about them, or even dreamt the plot for their novel.
Ahem, now I know one couldn't exactly write a novel about someones teeth falling out.

However have you ever had a dream that you've felt was that real, and have you ever incorporated them into your writing?
