He also could. Have seen a scary movie or previews of a scary show. Whatever it is I hope all is well
Wow, answer by Rockrose is really interesting. I have never heard of that. It is certainly worth researching!
However, I would also also ask Mom if he has had similar reactions with her, or recently seen any movies where this kind of thing was going on. Kids of his age are still not very good at communicating, and are very impressionable. So who knows what is going on?
I would certainly appreciate it if you get any more information that you share it so we could use it to help other kids who might have a similar problem.
Sounds like he may have "Alice in Wonderland Syndrome" or Todd's Syndrome, which in small children is often a symptom of mononucleosis. Both the zooming of the floor and the believe that the grass is taller than he is are described in this article.
