Sigmund freud...here i come...

Ok.. this may sound a little weird.. this just stuck me yesterday night.. i am sure everyone has these dreams in the early morns where the line between dreams & reality gets diminished...so that got me started off.. there have been so many times i have experienced this.. an example would be maybe you are dreaming about some elaborate sequence & the scene that is running presently is some car honking or some huge bell gonging in the distance.. and you suddenly wake up to realise that your alarm has gone off.. so the noise in the dream somehow is converted into a noise in reality...
So here is the twist.. did your subconcious hear the alarm before your conciousness did..and altered the dream to make the transition to reality smoother than an abrupt end of the dream?? Or was this just a coincidence?? ..and going furthur.. if the subconcious at some level reflects your emotions/reality in the dreams you see.. then is it toying with your conciousness.. you at some level know that what is going on is not reality..but your mind half belives the possibility of this being real..this is where the line starts to get thinner...
