Dreams...

Dreams are just fudged up reality. Is it correct? One of my best friend given me this subject. She just passed it as a thought for me, but I was long time wishing to write about it; write about dream. I am not believing, it is a fudged up reality; but it is some messages to us or strong feelings of inner mind comes as picture or some recent experience that lies in our declarative / episodic memory, while sleeping.

Let's start with sleep. I heard about sleep, if a person can sleep well without any disturbance by himself (except dream), he / she is one of the luckiest person. As we know sleep has different stages. It mainly divided into two distinct states known as non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM). These two states occur in a roughly 90 minute cycle, which is repeated 5 to 6 times at night and include four stages of NREM and REM. Stage 1 sleep is experienced as falling into sleep and is a transition stage between wake and sleep. Stage 2 sleep follows stage 1 sleep and is the "baseline" of sleep. Stage 3 and 4 or Delta sleep, is the "deepest" stage of sleep (not REM) and the most restorative. It is delta sleep that a sleep deprived person's brain craves the first and foremost. Stage 5 sleep -- REM (Rapid Eye Movement Sleep): a very active stage of sleep, because if one is to watch a person in this stage, their eyes are moving rapidly about.

So, what time the dream happens? As I said earlier, sleep has different stages and mostly from stage 5 we are going to stage 2. In this stage the dream happens. Our brain becomes so activated that we start to hallucinate and have what we call dreams. Our eyes move down to mid-line, just as in wakefulness, and they begin to move sporadically, many times in relation to what we are dreaming. In effect, we are a highly activated brain in a paralyzed body. This paradoxical state will last 10-20 minutes and then we "fall" back down into stage 2 again.

Each person has different kind of experience in the dream. But each person are dreaming in different way. If your dream is from declarative memories, people with amnesia shouldn't dream at all, or at-least dream differently than others do. But remember, people with amnesia can retain the information in their memory for very few minutes or called temporarily. It's no wonder that dreams are so illogical and full of discontinuity. But for me, what I dreamt are the messages for me and most of them are becoming practical now-a-days. Still I can remember, one of my dream was very strong, and it was a repetition of the day's activity. Some of the actions, stuck in our memory, without our knowledge; in short can say about dream. When we are in the stage of REM sleep, the brain refreshes the content of this memory cells and it becomes flash as looks like in a screen.
