Haunted Condo

On our first day at our vacation condo, I snapped this picture of my wife Joy. The camera captured what looks like an "orb". Orbs are commonly associated with paranormal activity. We booked the condo for only 2 people. Didn't we have a 3rd ghostly guest?  
 On the second night, we captured another "orb" close to the hallway floor. No other activity was ever detected. We have never experienced any kind of paranormal activity. Do you think there was a spirit in our condo?
