Second. Man forgets to 90% of their dreams. In fact, many have long known that the majority of dreams forgotten. But the strange thing is that so many of them is forgotten. How many interesting people miss.
Third. Dreams can see everything. Of course, everyone is different, therefore, just as dreams are all different. However, as mentioned above, people forget to 90% back. But this average. That is, there are people who remember more dreams, and there are those who do not remember at all. That is why they say that just do not dream.

Eighth. Vivid dreams. Proven that people who quit smoking, see more vivid dreams than heavy smokers or those who never smoked in my life at all.
Ninth. External factors influence our dreams. Oddly enough, but in my dreams we can often see what inspired extraneous sounds, smell, touch ... All this somehow affects sleep as a physiological process, and how to dream.
