Head like a recorder instrument (flute) PART 2

So last time I heard it at night then the Далее morning. This time, I was sitting in the living room and I heard it again in the same area that I did in the morning and it's so weird because nobody else hears it and my sisters room is right Далее to it!! It didn't feel like a flashback because I didn't sdd anything. I never go outside to my backyard so I probably have 0 fairies. It was around 4:40pm Peter doesn't come that early?

Please read it all, thanks!!!
