A very active night

Marty and I went to bed sometime around Midnight last night. We had both just fallen asleep when our Female pit bull woke us up growling out in the sunroom.Marty calls her by her name, so she runs into our room barking now, and goes directly under the covers shivering. I sort of half figured that whatever had frightened her was gone by now. (That seems to be how these things work.) So there was no reason to get up. We both went back to sleep only to have our male Boston wake us up a while later growling. I was getting annoyed at this point.Marty calms him down, and we both go back to sleep.Then Marty is waked by what he called" a lot of activity" He heard our dryer run, with a button shirt in it. (I know you all know what this sounds like, as the buttons clink inside the dryer on rotation.) But the dryer wasn't on. As he lay there listening, this noise turned into the sound of champagne glasses being clinked together. But he described it as being rhythmic.He finally fell asleep listening to all the strange noises. Where I sat bolt upright in the bed. Something had startled me from sleep. But I didn't hear anything. I listened for a bit, But the house seemed entirely quite. I turn to look at the clock. 3:30 am. Great. I snuggle back into the covers for a few more hours of blessed quietness.
