2001: A Space Odyssey/ A Dream

Do your remember in the movie that scene near the end where this guy is in this room, it's like a posh hotel room, everything you need, a fridge with food, basic furniture including a bed, a complete bath. But, there's no doors, no windows, no phone, no telly, no sound. he's totally alone. he's just there sitting or laying in bed.
For the past few weeks I've this dream every night that I'm that guy.
