A childhood belief about creepy crawlies

One day in the front yard when I pointed to the shell of a garden snail and asked my mom what it was, she said it was the snail's house. I imagined that when the snail retreated into his house he had all sorts of tiny furniture inside. I pictured the snail lounging on a couch, watching TV, and there was a little kitchen, and also a bedroom. The logistics of this made complete sense to me, because I believed that when the snail went inside his house he got smaller in the same way as when I saw the character Jeannie shrink down in size when she went into her bottle on the "I Dream of Jeannie" TV show. During the scenes where Jeannie was shown sitting on her pillows inside her bottle, you could see the groovy-looking interior walls of the bottle, and I imagined that same appearance for the interior walls of the snail's house.
