Female voice from behind at the window at night

Right now I'm lying in the dark, in bed on my side, back to the window, reading a post about a witch granny and her grandson at a dacha from a previous thread, it's 00:25 on the clock, and from behind me, from the window side, comes a female voice and something like "umrm got into the habit", very much like an old person's, but a pleasant voice without hoarseness or anything.
Fuck, mine dropped, anons. My thoughts have never spun that fast in my head. First thought about that granny, second thought that it's the cat, she makes sounds in her sleep or when she stretches, but not like that, third that it's the wife, but I heard her snoring at that moment, it didn't stop. Fucking hell, goosebumps all over and my soul in my heels. Okay, still with the certainty that it's the cat, lying somewhere, I turn around and sure enough she's lying in her spot, but not asleep... Went to the shitter, pissed myself from fear, and checked everything with a flashlight while I was at it. Thanks a lot, cat, damn, gave me a scare.
While I'm typing this post, the cat made her usual sounds 3 times and I realize they're not like that one, neither in volume nor in sound. Okay, probably got too absorbed in reading, hallucinated. Well, and the cat would've reacted to it, probably...
