Dreaming a dream?

Dreams are a strange thing. It fascinates me how they work and how your subconscious can overcome all rational thought, desires and morals to put you in impossible situations and frankly, sometimes embarrassing predicaments! I have, on more than one occasion, dreamt about kissing a co-worker, once even my boss and whilst he is a great boss and person he's not who I would choose for the man of my dreams. So what makes our brains, or our subconscious (I say "our" in the hope I am not the only one dreaming inappropriate scenarios!) do these things in dreams, that in real life just wouldn't happen. Some people can say its your subconscious desires but I don't believe that, I am in a happy and committed relationship and have no desire to kiss my boss - if it were to be anyone, I would be dreaming about David Beckham!

Dreams can be frustrating events, I have often woken up feeling, that's a nice dream and no matter how hard I try I can't get back into them. Or dreaming and knowing its a dream and trying hard to make things happen, like when you need to scream and nothing comes out, or when you want to run and you can't move. Then there are the ones I have during the mornings I lie in, drifting in and out of sleep, they are almost like short stories. I find these dreams much more malleable. I had about 3 or 4 this morning, one where I was in my grandparents house and my grandma was there (she died last month) and I wanted to hug her and I managed to make myself do that in the dream. I always realise these dreams are dreams whilst they are happening. I think the morning dreams are much more susceptible to being changed by my conscious mind. Perhaps they are in fact a "snooze-dream" a cross between a full day dream and a night dream.
