Can they pick up solid objects or somehow talk into a phone or something?
Explanation: Well, I was on the phone with my friend Steph and all of a sudden we heard a sort of garbled sound like someone talking except it sounded like a man and my brother and Dad weren't there and my friend's brother is 8 years old. We both heard it so we hung up the phone so I could see if my bro was home. I went downstairs and I heard some sort of 'whooshing' sound. That freaked me out...
