I saw a show once where this man steps into a cabinet and snow starts swirling around him. Later in the show someone wipes circles on the glass and finds him. The only other thing I remember is that a woman was upset by all this.
You don't say when you saw it, but I'm wondering if it's the "Silent Snow, Secret Snow" episode of Night Gallery, released in 1971.
Psychiatrist Joel Winter investigates the claims of his asylum patient, hippie Gideon, that a pretty girl from a nearby farm is killing his patients./The Haslemans worry when their son becomes obsessed with snow that's talking to him.
