My friend saw a movie when she was very young and is bugging me to help her find the title. It's about a little boy who rolls down a ditch during some family picnic thing. He has an older brother. He wakes up and finds himself in some kind of institution or weird building. They perform tests on him. He escapes with these other creatures from other planets but there's one main creature helping him. There's some kind of danger involved with transporting them back to their world of origin. At the end, the boy is back in the ditch and no one knows he was even missing as his older brother finds him.

I think it's "Little Monsters" with Ben Savage and Howie Mandel.

It sound something like The Navigator, ask your friend if it had an alien spaceship in it that talked
