I have been trying to figure this movie out for years. I believe it to be a movie and not a television show.
I remember a boy sleeping in his room who was then visited by midgets in the middle of the night and bedroom walls moved around.
I remember them being in a field and there being a rainbow they went into the rainbow to reach the end, as the passed through the colors of the rainbow the filter on screen would change, I remember loving this.
The next part I believe to be from the same film. They went to a different land, and there were a King and Queen, and the people had these large paint vats where they would drop a person into the paint/goop and they would come out transformed as a anthro butterfly.
I was about 4/5 years old when I saw this film. I watched it at home it would have been about 1989/1990 approx. So released before that. It was in color.
Any help to solve this or part of the mystery would be helpful 🙂
