Ok guys. Thanks in advace. This is some 80s movie I guess. I watched it 15 yrs ago it seems. Basically, a boy befriends with an alien, and traveling in its ufo kind of stuffs. & in the climax, the boy wakes up as if it was all a dream and he sees a star blinking in the sky (ufo) making the boy think whether it was all a dream or something really happened. Its not Mac & Me... I searched almost everwhere, can't find..

Possibly Flight of the Navigator (http://www.imdb.com/title/tt0091059/)

Let me checkk.. thanks

Yeah flight of the navigator
