I've been hearing a "knocking" noise, usually 3 knocks each time...I've been awakened by it a few times, have gotten up thinking it was my mothers nurse at the door, only to find noone there. I don't keep the t.v. on in our room, so I know its nothing like that, plus Gizmo (my dog) barks when it happens so he hears it too...now, it may just be like a loose gutter or something like that, but its just funny that its always "3" knocks each time. Also, the other night, my husband & I were watching Ghost Hunters (how ironic, I know! lol) & it was just about to go off when we both heard 3 'clinks' or whatever you'd want to call it, on the glass light fixture in the dining room, which would have been right behind us. Gizmo was on the couch with us, Moma was asleep, so that really has us puzzled...but it definitely sounded like someone tapping on glass with something, I'm sure you know the sound I'm talking about, & again, it was "3" times...So, any ideas? =} Kris
