Ok, I can’t remember a lot about this movie, all I really remember is that the main character was a kid who was scared of his basement because of someone living down there called “Mr.Nobody”. At the first when he goes down, the furnace goes all scary and he runs back upstairs. Mr.Nobody follows him around for the rest of the movie, and it ends in a playground with a lot of balloons.
Was it a kids movie? It’s not 100% but the first thing I thought of was Mr. Boogedy

I sort of remember a scene like that too, but can’t think of the movie. It also, very faintly resembles “The Shadow Man” episode of the Twilight Zone series.
That sounds familiar. Could it be an episode of Are You Afraid of the Dark? or Goosebumps?
