It's not important, but I sometimes have viewed balloons after that I came down with a cerebral hemorrhage. I had known a similar story.
For example, a man could view ghosts. So I felt easy because I don't like horror.
They are connected with human's heads.I was bewildered when I viewed them first time.
After a while, I knew theirs true characters.
Sometimes, I've found a balloon with tattered string.
Its effects on human's memory which connected with that string.
When a tattered string broke, a balloon connected with that string fry off in the sky. At the same time, A person who had been connected with that balloon lose their memory.
