My husband left the water running from the hose and the well is dry!
Give it time. Most wells have a pretty consistent "production rate" based on underground geography (maybe there is a better word).  I've grown up around wells all my life and every one is different. 

Give the well time to recharge (let water refill the well drill pipe. ) 

Because the well ran dry and the above ground pump started "sucking air" it may need to be re-primed. Not a hard procedure to do. 

We can help you with specific instructions if you let us know more details of your well system, pump, well logs (drilling logs) drawdown tests.  But esp. the details of your pump so we can help you safely restart it.   Some wells with limited capacity have controls in place to prevent damage to a pump in the case of excessive draw.  That would be another important thing for us to know.
