Indeed dreams are very important, they keep us sane, mentally and are an outlet for emotional problems and issues that we sometimes cannot deal with during our (busy) day.
A few days ago I started using ZMA capsules, a side effect of this supplement is vivid dreams and deeper sleep and it sure does that..never slept so well in my life!
Dreams do help us immensely, although they arent real...they do help in many different ways. A good write, short but something different -- I liked it!
