With all due respect to Mr. Dahl

When Jon woke up in the morning, he found himself trapped under a giant cloth...He shook around and pushed, and freed himself...discovering he was in a giant version of his own bedroom. His arms were also gone...replaced by bird wings. "Damn Karyn," he muttered. "I don't even have hands anymore.." He launched into the air, instinctively knowing how to fly and flew around the house. He was bird-sized...and the house seemed to have remained people sized... "Yay!!" Mikey said, cutting in front of him, wings fluttering. "Watch it, birdbrain..." Jon said. He was not a morning person, not while he was turned into a little human with bird wings. Was this some sort of stone glitch?
