Garage Door Opener Process

Sometimes you store things in your garage, so obviously you need to open the garage door. A lot of people have garages attached to their houses, or put their cars in them, but if you don't do either of those things then your garage can become quite the mausoleum of old junk and interesting finds. Kind of like the room of requirement in Harry Potter. This room, also sometimes known as the Come and Go room, possesses some degree of sentience, as it can sense exactly what the person entering it needs (and is asking for) and shapes its insides to fit that description. Harry and his friends of ten use it for training ground and meeting spot for the club Dumbledore's Army in the fifth book. But its resemblance to a garage (and its beautiful scrolling wooden double doors can be replicated in a garage door should you so choose) is greatest when it as serving as "the place where things are hidden".
Presumably, wizards and witches have been hiding things in there for centuries. Apparently this specific room as remanifested itself over and over in times of need. And the collection of stuff in there is really impressiv,e ranging from furiature to magic brooms to other magical items to crazy plants to lost diadems. Harry himself used the room SPOILER ALERT!! to hide his marked up copy of his potions textbooks that used to belong to the Half Blood Prince (who was really Severus Snape, who was really a good guy in the end.) But the stacks and stacks of junk in the Room Where Things Are Hidden really resemble the inside of my garage. It's kind of alarming. And though, in the seventh book, Harry and his friends torch the insides of the room (which is really tragic, considering how many priceless items they probably destroyed) that is not an option for me.
