LOL Vanessa!
Nah, as long as the bulbs are fat and healthy, it's fine, just gone dormant. It won't be too long before you'll see a little nubbin at the bottom of the bulb that will then grow into another leaf bearing large bulb.... essentially a clone of the mother bulb.
Watch for roots to start from the bottom of the new bulb, when they are an inch or so long you can set the plant down in the top of new media and start watering.
Yeah for a while I didn't know that many orchids are deciduous either and it turned out I was being all heartbroken for what was normal orchid behaviour!
I think I tossed away several perfectly healthy dendrobiums this way.
