It's a movie that I use to love when I was little but I never knew the title and barely remember what happens in it anymore.
The movie is from the 80'-90's, and I believe it pretty much starts with the boy buying a new bicycle and when he gets home he leaves it outside, but the next day he doesn't find it there.
He starts wondering where it went or how it disappeared. Eventually, more things in his house start being sucked on through his big antenna in the front yard of his house. At some point there was this huge wind (or some kind of gravitation) pulling him towards the antenna and he had to hold on to one of the columns in his porch but now his feet were hanging in the direction of the antenna. I think eventually the antenna sucked him in. Then, I believe, he got transported inside the tv (or some kind of parallel universe)
Now, what I'm about to say, I'm not sure if it's also from this movie or I'm confusing it with another one.
But what happened is, his parents were also missing (I think he thought they were sucked by the antenna and he had to go in to rescue them). At some point he is in this store at the mall or something like that and time is running out to find his parents. He sees them far away and he starts running as fast as he can to get to them. But I don't remember what happens after that.
