This is a movie or show Im trying to find the title for. I think it begins with a kid asleep in his bed and he is awakened by a knight(?) on a horse that is jumping through his wall over his bed. He sits up in his bed and he is now outside in a forest. Little dwarfs appear and that's all I remember.

It is, of course, Time Bandits (http://www.imdb.com/title/tt0081633/).
