A series of things happen to us during sleep. During sleep when we dream our muscles are relaxed, brain feels refreshed, heart beat becomes slower, blood pressure and temperature of our body fall down.
Dreams are a crucial activity of the mind during sleep. They rejuvenate our mind. They are important because they help us to sleep, doctors say that they reveal much about the problems we are facing, and also provide solutions to concerned issues. But the thing to stay in mind is that dreams can't tell our future, though they recover our body and mind from fatigue, they take us faraway from all the disturbance yet they just can’t tell us our future. Sleep has magical ability because it takes us into a wierd world. It is a pleasing and commonest experience for all.
