Dreams

My understanding about dreams are little simpler than the popular ones. I personally feel that, just before the moment you’re falling into sleep, whatever was in your mind becomes concentrated. I am not saying that is the same thing we see in our dreams, but that is where we will start it. Let me explain this a bit. You should know that human mind do not or probably can not think just one simple thought at a time. There are numberless threads of thoughts going on in your mind at all time. Some of them come up to the surface, others are just below that, while the rest seldom comes to the front, which we call our background thinking or often termed as the sub-conscious mind. So, when you are falling asleep you will have a bunch of thinking threads running inside your mind and possibly some of them are on top (on the surface). Now what we call sleep starts when these thinking threads start to reduce in number. You will gradually loose most of the threads and only a few of them, possibly only one will sustain. That whether this thread should be from one of the sub-conscious processes or the conscious ones is arbitrary to me. But whatever that is, that will be the start of your dream. And from that moment on you will think only that flow so deep that it will seem almost real to you. And that is your dream!
You might reasonably question: “Well if we have thinking threads all the time and also when before going to sleep, then how come we don’t experience dreams every time we sleep?” My answer is, sometime the thinking thread that will survive in your sleep might be a very weak one and will not produce enough results for your brain to make sense of it. Or it might have such low impact on your nervous system that you won't simply remember it when you wake up.
Explaining all these, the meaning of dreams are still not described, I think. That is probably a different question which explains the very nature of what we think and why. And that is obviously one of the most puzzling questions ever asked by anyone.
