i really hope you can ask her & get it /g
im not sure what sounds youre hearing but im used to hearing sounds at night that make me extremely paranoid, i try to rule it out and decide what is making that sound.
idk if thats somehting youd like to do but most of the sounds i hear are, the house settling/expanding or smth due to temperature, cars very far away, people snoring, any electronic buzzing/hum when i was younger i heard this unbearable beeping/humming sound in my pillow, i was terrified, but it turns out it was my moms cell phone cord 2 rooms away.
sound can travel in a lot of funky ways but i promise you are safe, and nothing bad can or will happen when you go to bed, idk. /gen /pos
tldr: sound is funkee and can travel really far and ur safe /lh /gen
(apologies if this doesnt make a ton of sense im about to head to bed myself /lh)
