DID HE...?!

I put out 3 shells on my windowsill. My window has a fly screen and my actual window is half open with the shells between the window and fly screen if that makes any sense. Well the shell in the middle got moved like upwards and sorta tilted.. Is it a sign? (Btw I'm the girl who had a dream about him) I asked my sis which is in the same room as me she swore she didn't touch it. I'm pretty sure before I went to বিছানা it was how I left it and my sis was still asleep when I woke up and saw it.. A SIGN? Is it a sign did he accidentally সরানো it when he came into my room??
