Talk about a memorable, enjoyable, or strange dream you\'ve had?

I remember of the strange but realistic dream that I\'ve had a long time ago. I and my family have moved to where we live about 18 years ago. There is a river flowing near our house, called Tancheon flowing from the southern part of Gyeonggi-do toward Seoul. The riverside road is good for people to walk, ride bicycles, and exercise, so our family often went there for a walk, toward the direction of Seoul. One day in my dream, I and my mother walked along the river toward the opposite direction of Seoul, and encountered a wall made of concrete blocking the river. I felt very sad that I have reached the end of the river, touched the wall, and went back. It was so realistic that I believed that the concrete wall truly existed! One day my mother suggested to walk along the river toward the opposite direction. I insisted that the road is blocked with a concrete wall. I could believe that it was a dream after walking with my mother to that direction and seeing the endless-looking wide river.
