Flying tortises at 10:19?

So I had a dream early this morning that I was in my bedroom looking at pictures on my wall that suddenly seemed possessed by something evil. I was actually getting freaked out in my dream by these pictures. Then I looked outside my window and saw a blue star and thought "that must be Sirius", but then I saw a red star and thought "no, THAT must be Sirius", but then both of those and many other blue and red stars were coming closer and turned out to be tortises in blue and red wing sets (some had blue and some red) and when they hit the ground, they lost their wings and walked off. I knew then that it was a "night of the flying tortises", and that it had happened in the past and was always unpredictable when it would occur. Seeking to find a pattern, I looked at the clock and saw it was 10:19, which I know has some significance (it didn't change at all when I glanced back at it). My room was still dark, but I rushed through it to the main hall (the "evil" pictures had lost their power)
